Fibromyalgia Linked to Overactive Brain Networks

By Pat Anson, Editor

Many fibromyalgia sufferers have been told that the pain is “all in their head.” New research indicates there may be some truth to that, and that overactive brain networks could play a role in the hypersensitivity of fibromyalgia patients.

Fibromyalgia is a poorly understood disorder characterized by deep tissue pain, fatigue, headaches, mood swings and insomnia. There is no known cause and successful treatments have been elusive.

In a lengthy study published in the journal Scientific Reports, an international team of researchers at the University of Michigan and in South Korea report that patients with fibromyalgia have brain networks primed for rapid responses to minor changes. This abnormal hypersensitivity is known as called explosive synchronization (ES).

"For the first time, this research shows that the hypersensitivity experienced by chronic pain patients may result from hypersensitive brain networks," says co-senior author Richard Harris, PhD, an associate professor of anesthesiology at Michigan Medicine’s Chronic Pain and Fatigue Research Center.

In ES, a small stimulus can lead to a dramatic synchronized reaction throughout the network, as can happen when a power outage triggers a major grid failure or blackout. Until recently, this phenomenon was studied in physics rather than medicine. Researchers say it's a promising avenue to explore in the quest to determine how a person develops fibromyalgia.

"As opposed to the normal process of gradually linking up different centers in the brain after a stimulus, chronic pain patients have conditions that predispose them to linking up in an abrupt, explosive manner," says first author UnCheol Lee, PhD., a physicist and assistant professor of anesthesiology at Michigan Medicine.

The researchers tested their theory by conducting electroencephalogram (EEG) tests on the brains of 10 female patients with fibromyalgia. Baseline EEG results showed the patients had hypersensitive brain networks, and that there was a strong correlation between the degree of ES conditions and the self-reported intensity of their pain during EEG testing.

Lee's research team and collaborators in South Korea then used computer models of brain activity to compare the stimulus responses of the fibromyalgia patients to those of healthy ones. As expected, the fibromyalgia model was more sensitive to electrical stimulation.

"We again see the chronic pain brain is electrically unstable and sensitive," Harris says.

Harris says this type of modeling could help guide future treatments for fibromyalgia. Since ES can be modeled outside of the brain in computers, researchers can test for influential regions that transform a hypersensitive network into a more stable one. These regions could then be targeted in living humans using noninvasive brain modulation therapies such as transcranial magnetic stimulation, which is currently used to treat fibromyalgia and depression.

“We expect that our study may ultimately suggest new approaches for analgesic treatments. ES provides a theoretical framework and quantitative approach to test interventions that shift a hypersensitive brain network to a more normal brain network,” researchers reported. 

“It may be possible to convert an ES network to a non-ES network just by modulating one or two hub nodes. Indeed, transcranial magnetic stimulation and/or transcranial direct current stimulation may be improved by ‘targeting’ these sensitive hub nodes. The application of deep brain stimulation to critical nodes that could modify ES conditions is another therapeutic possibility that could be explored.”

The research was funded by the Cerephex Corporation, James S. McDonnell Foundation, and the National Institutes of Health

Lyrica and Neurontin Use Triples

By Pat Anson, Editor

The use of gabapentin (Neurontin) and pregabalin (Lyrica) has soared in the United States, with little attention paid to their safety and effectiveness, according to a research letter published in JAMA Internal Medicine.

Gabapentin and pregabalin belong to a class of nerve medication known as gabapentinoids, which are increasingly prescribed as alternatives to opioids in treating neuropathy, fibromyalgia and other types of chronic pain.

In an analysis of health data for nearly 350,000 patients, researchers found that the use of gabapentinoids more than tripled in the past decade, from 1.2% of patients in 2002 to 3.9% in 2015.

Use of the drugs was concentrated in older patients with numerous other health problems, who were often co-prescribed opioids or benzodiazepines, a class of anti-anxiety medication.

“The combination of a dearth of long-term safety data, small effect sizes, concern for increased risk of overdose in combination with opioid use, and high rates of off-label prescribing, which are associated with high rates of adverse effects, raises concern about the levels of gabapentinoid use,” wrote lead researcher Michael Johansen, MD, of OhioHealth, a large non-profit health system based in Ohio.

“While individual clinical scenarios can be challenging, caution should be advised in the use of gabapentinoids, particularly for those individuals who are long-term opioid users, given the lack of proven long-term efficacy and the known and unknown risks of gabapentinoid use.”

JAMA INTERNAL MEDICINE

Johansen’s research adds to a growing body of evidence that pregabalin and gabapentin are overprescribed and being abused. A recent study by Canadian researchers found that there was “no clear rationale” for the off-label use of the drugs and warned that they have a “significant risk of adverse effects” such as dizziness, fatigue and diminished mental activity.

Lyrica (pregabalin) and Neurontin (gabapentin) are both made by Pfizer and are two of the company’s top selling drugs, generating billions of dollars in annual sales. Lyrica is approved by the FDA to treat diabetic nerve pain, fibromyalgia, post-herpetic neuralgia caused by shingles and spinal cord injuries; while Neurontin is approved to treat epilepsy and post-herpetic neuralgia. Both drugs are also widely prescribed off label to treat back pain, depression, migraine and other conditions.

Sales of pregabalin and gabapentin have risen steadily in recent years, in part because of CDC prescribing guidelines that recommend the two drugs as alternatives to opioid pain medication. About 64 million prescriptions were written for gabapentin in the U.S. in 20l6, a 49% increase in just five years.

“We believe… that gabapentinoids are being prescribed excessively — partly in response to the opioid epidemic,” Christopher Goodman, MD, and Allan Brett, MD, recently wrote in a commentary published in The New England Journal of Medicine. “We suspect that clinicians who are desperate for alternatives to opioids have lowered their threshold for prescribing gabapentinoids to patients with various types of acute, subacute, and chronic noncancer pain.

Gabapentinoids are increasingly being used recreationally by addicts who have found the medications enhance the effects of heroin and other opioids. Lyrica and Neurontin have been linked to heroin overdoses in the United Kingdom, where prescriptions for both drugs have soared in recent years. 

Painkillers Raise Risk of Obesity and Hypertension

By Pat Anson, Editor

Commonly prescribed painkillers such as opioids and gabapentinoids  -- a class of pain medication that includes Lyrica and Neurontin – significantly raise the risk of obesity and high blood pressure, according to a large new study published in PLOS ONE.

British researchers analyzed health data on over 133,000 people, comparing the Body Mass Index (BMI), waist circumference, blood pressure and sleeping habits of patients taking pain relievers to those who did not. The study is believed to be the largest to look at the effects of painkillers on overall health.

“In the last two decades there has been a significant increase in the number of people being prescribed both opioid and non-opioid medications to treat chronic pain,” said lead author Sophie Cassidy, PhD,  a research associate at the Institute of Cellular Medicine, Newcastle University. “We already know that opiates are dependency-forming but this study also found patients taking opiates have the worst health. Obesity rates are much higher and the patients reported sleeping poorly.”

Those taking opioids were 95% more likely to be obese, 82% more like to have a “very high” waist circumference and 63% more likely to have hypertension compared to the control group.  

“There could be a number of possible mechanisms by which opioids might be associated with weight gain. Sedation might decrease physical activity and therefore reduce energy expenditure, those in our cohort taking opiates were less active, and those taking both opiates and other sedative drugs were the least active. Opioids have also been shown to alter taste perception with a craving for sugar and sweet foods described,” Cassidy wrote.

“These results add further weight to calls for these chronic pain medications to be prescribed for shorter periods.”

Patients who took gabapentinoids were also more likely to be obese, have a bigger waist and higher blood pressure compared to those not taking the drugs.

Gabapentinoids are commonly prescribed as alternatives to opioids to treat neuropathy, shingles and fibromyalgia, although many patients complain about side effects such as weight gain, depression and anxiety.

As PNN has reported, gabapentinoids are also coming under scrutiny because they are increasingly being abused. Lyrica (pregabalin) and Neurontin (gabapentin) are being reclassified as controlled “Class C” substances in the UK, following a spike in the number of deaths involving the medications.

Last week, the West Virginia Board of Pharmacy designated gabapentin as a “drug of concern,” after overdoses in the state involving gabapentin rose from 36 deaths in 2012 to 106 in 2016.  Ohio, Pennsylvania and Kentucky have also reported increases in fatal overdoses involving gabapentin.

FDA Approves Extended-Release Lyrica

By Pat Anson, Editor

The U.S. Food and Drug Administration has approved a new extended-release version of Lyrica for the treatment of neuropathic pain. Lyrica CR is designed to be taken once a day, instead of the two or three doses recommended for Lyrica’s original formulation.

“Lyrica CR was developed to offer patients an effective treatment option with the convenience of once-daily dosing,” said James Rusnak, MD, Chief Development Officer in Pfizer’s Global Product Development. “It provides an important option for patients and health care providers managing these often debilitating pain conditions.”

Pfizer said the effectiveness of Lyrica CR was established in a clinical trial of over 800 patients with neuropathic pain. Patients who took Lyrica CR had a 74% reduction in pain, compared to about 55% who took a placebo. The most common side effects of Lyrica CR were dizziness, somnolence, headache, fatigue, peripheral edema, nausea, blurred vision, dry mouth and weight gain.

Lyrica (pregabalin) is one of Pfizer’s top selling drugs, but the company will likely face strong competition from cheaper generic versions of pregabalin when its U.S. patent expires next year.

Pfizer is undoubtedly hoping that current Lyrica users will switch over to the new extended release version, which will have full patent protection for many years to come. The company did not release any information on the cost of the new drug, which is expected to be available in January.

Unlike the original formulation of Lyrica, which is widely prescribed to treat fibromyalgia, Lyrica CR is only approved to treat nerve pain caused by diabetic peripheral neuropathy and postherpetic neuralgia caused by shingles. But that won’t stop doctors from prescribing it off-label to fibromyalgia and other chronic pain conditions.

Pregabalin Under Scrutiny

The extended release version of Lyrica comes at a time when pregabalin is drawing new scrutiny from researchers and doctors who believe the medication is over-prescribed and being abused. Pregabalin belongs to a class of nerve drug known as gabapentinoids, which are increasingly being prescribed as alternatives to opioid pain medication.

 “We believe… that gabapentinoids are being prescribed excessively — partly in response to the opioid epidemic,” Christopher Goodman, MD, and Allan Brett, MD, recently wrote in a commentary published in The New England Journal of Medicine. “We suspect that clinicians who are desperate for alternatives to opioids have lowered their threshold for prescribing gabapentinoids to patients with various types of acute, subacute, and chronic noncancer pain.”

As PNN has reported, the World Health Organization and the FDA are also investigating reports that pregabalin is being abused. Addicts have learned pregabalin enhances the effects of heroin and other opioids.

“Reports indicate that patients are self-administering higher than recommended doses to achieve euphoria, especially patients who have a history of substance abuse, particularly opioids, and psychiatric illness. While effects of excessively high doses are generally non-lethal, gabapentinoids such as pregabalin are increasingly being identified in post-mortem toxicology analyses,” the FDA said in a recent notice published in the Federal Register.

The warning label for Lyrica CR will caution users that the drug can be abused.

“Patients should not drink alcohol while taking Lyrica CR. Patients may have more dizziness and sleepiness if taking Lyrica CR with alcohol, narcotic pain medicines, or medicines for anxiety. Patients who have had a drug or alcohol problem may be more likely to misuse Lyrica CR,” the label warns.

Pregabalin is classified as Schedule V controlled substance in the U.S., which means it has a low potential for abuse.

A Pained Life: It Never Hurts to Ask

By Carol Levy, Columnist

Recently a documentary was released on Netflix about Lady Gaga.  A part of her story is that she has fibromyalgia. 

I have not seen the film, but understand she devotes a little time to detailing and showing how she deals with chronic pain, both physicially and emotionally. Articles and posts abound in chronic pain social media about the film and Lady Gaga's pain.

The odd thing is many of the writers start by complaining that people don’t understand their pain, why they have to take drugs, and why they can't do many things that seem so easy to everyone else. 

Then, strangely, they do exactly what they complain happens to them.  They express doubts about Lady Gaga’s diagnosis, wonder if she is malingering, and say she can't really have fibro because her level of suffering and disability is not the same as theirs.

It seems we in the chronic pain community want to have our cake and eat it, too.  We want to have the discussion about chronic pain made public. We want awareness. But the awareness has to be exactly the way we want it or we don't want it at all

SCENE FROM "GAGA: FIVE FOOT TWO"

Many in the pain community express feelings that anything in the public eye that even hints of chronic pain should be about the person's struggles and life interruptions caused by pain.  Lady Gaga is a case in point. 

“She didn’t talk enough about fibro,” writes one person, others echoing the sentiment. “I thought from all the hype I heard it was going to be about that.” 

It would have been terrific if Lady Gaga had devoted more time to her disease and its effects on her life, but then that really was not the point of the documentary.

“Some of the film may actually be hurtful to some of us, as it shows her being able to do very physical things that are often beyond many of us as we struggle with the pain. If you have watched her perform she is not a sedentary singer,” wrote one poster on social media.  

Maybe it is worth asking her. Could you do something more, maybe another film or even just a commercial, that would bring needed attention to chronic pain and its effects on our lives?  

Last month was Pain Awareness Month, and it went by with almost no awareness or notice at all.  Lady Gaga might be the awareness hook that we need.

But we need to stop lamenting, hoping and complaining that no one is doing enough.  It is past time to take the bull by the horns.  We have to do it ourselves.  As they say, if not now, when? If not us, who?

And who knows? If someone or a bunch of someones ask Lady Gaga or another celebrity to be our voice, they might actually respond. If we don't ask, we’ll never know if they want to help the pain community.

The worst they can say is no.  And maybe, just maybe, we can get a “Yes.”

9 Holistic Approaches to Relieve Joint Pain

By Nicole Noel, Guest Columnist

Whatever your ailment may be, holistic medicine has an answer.

A therapeutic method that dates back to early civilizations, holistic medicine takes into account the mind, body, emotions and spirit -- with the aim of helping patients achieve or restore proper balance in life and prevent or heal a range of conditions, including musculoskeletal pain. Holistic treatments offer a ray of hope for many patients suffering from arthritis, osteoporosis, fibromyalgia and other conditions that cause joint pain.

Not all alternative medicine is created equal, and some natural healing methods will produce better and quicker results. If you want to treat arthritis and other joint aches with holistic treatments, here are a few natural pain relievers you can try.

1. Tai Chi

A low-impact activity that can increase range of motion and strengthen joints and surrounding muscle tissue, tai chi is an ancient physical and spiritual practice that can help arthritis patients soldier through their pain.

According to a 2013 study, tai chi can relieve pain, stiffness, and other side-effects of osteoarthritis. In addition to pain relief, tai chi can help improve range of motion and alleviate joint pain for people living with fibromyalgia and rheumatoid arthritis.

2. Yoga

Another ancient technique which promotes natural healing, yoga is perfect for individuals suffering from lower back and joint pain. Gentle stretches and poses opening the joints can help prevent and alleviate chronic soreness in the shoulders, hips, and knees.

A form of yoga called mudras utilizes a series of hand gestures to increase energy, and improve mood and concentration.

3. Massage

An invigorating massage with warm essential oil can help many conditions, and joint pain is one of them.

By enhancing blood flow, relaxing the muscle tissue and soothing inflammation, a well-timed massage can ease joint stiffness and increase range of motion in individuals suffering from arthritis, fibromyalgia, and osteoporosis.

4. Acupuncture

A 2013 review of medical studies has shown that acupuncture can help relieve musculoskeletal pain caused by fibromyalgia. By activating the body’s natural pain relief system and stimulating the nerves, muscles and connective tissue, acupuncture can relieve joint aches for people who are resistant to other holistic pain relief techniques.

A 2010 study found that acupuncture can also be a beneficial for peripheral joint osteoarthritis.

5. Diet Changes

An apple a day may or may not keep the doctor away, but a custom-tailored diet can help you with joint pain. Nutritional tweaks can begin with increased intake of chondroitin sulfate, glucosamine, and Omega 3 fatty acids, which can reduce joint pain in arthritis and osteoporosis patients.

To ease joint problems, your pantry should be stocked with foods that promote healing and reduce inflammation, such as onions, carrots, and flaxseed. Herbs and spices such as turmeric (curcumin) and cayenne pepper can also help with pain relief.

6. Aromatherapy

If you think pain relief can’t smell good, you’re mistaken. Studies have shown that peppermint and eucalyptus oil can reduce swelling, pain and discomfort in patients with inflamed joints. For joint soreness and stiffness caused by arthritis, aromatherapy experts recommend regular application of myrrh, turmeric, orange, or frankincense oil to ease inflammation and pain, and to increase range of motion.

You can also combine aromatherapy with heat and cold treatments.  Be sure to keep the tender joints elevated during treatment to reduce swelling.

7. Spa Treatments

Few things can beat the appeal of a full-scale spa experience. If you’re suffering from knee, hip, shoulder or elbow pain and other holistic methods haven’t helped, try balneotherapy, which combines aqua massage with deep soaks in heated mineral water and medicinal mud baths.

One study found that balneotherapy significantly reduced knee and back pain in older adults.

8. Aquatic Sports

If you don’t want to immerse yourself in mud, you can supplement your holistic pain therapy with water aerobics, swimming, aqua jogging or aqua spinning. According to a 2014 study, water exercises can ease pain and improve joint function for osteoarthritis patients.

Additionally, a 2015 study found that aquatic circuit training can help relieve knee pain in cases of progressed osteoarthritis.

9. Capsaicin cream

Another natural treatment for joint pain and stiffness is homemade capsaicin cream, which can help reduce swelling and increase range of motion. To stay on the safe side, you should be careful when handling hot peppers when preparing the cream, and avoid using it on sensitive and damaged skin.

As our bodies age, joint pain can become a chronic. If you don’t want to take your chances with conventional pharmaceuticals, you can always turn to holistic medicine for answers and help. When musculoskeletal pain hits home, one or more of these holistic treatments can help.

Can Analgesic Creams Treat Chronic Pain?

By Pat Anson, Editor

An Irish opera singer who suffered from the same chronic pain condition as Lady Gaga claims she was “cured” of fibromyalgia by rubbing a topical cream on her body.

“I was amazed that within a few hours of putting the cream on my knees and my neck, the pain started to ease and the swelling abated slightly,” Liz Farrell told the Daily Mail. “By the end of the first week I was able to start reducing my daily intake of painkillers.”

Farrell was diagnosed six years ago with fibromyalgia – a condition that causes widespread body pain, fatigue and insomnia. The 40-year old singer tried a cocktail of drugs that included tramadol, Cymbalta, Lyrica and anti-inflammatory medications, but her pain only grew worse and she stopped performing.

Then Farrell started using Celafen, a drug-free topical cream that contains menthol, Vitamin E and a patented blend of fatty acids called Celadrin, which lubricates cell membranes and has anti-inflammatory properties.

“I felt completely normal again, like my old self. I was able to start driving again, which I’d not been able to do for two years,” said Farrell, who recently started performing again. “It has been like coming to the end of a prison sentence, to have that freedom back again.” 

"I can’t begin to imagine how Lady Gaga has been coping with her stage performances with this crippling condition; she must be a very brave lady.”

Lady Gaga’s battle with chronic pain has received a great deal of media coverage lately. She recently cancelled concert appearances in Brazil and Europe to focus on her health.

Would Celadrin help Lady Gaga? Would it help you? The reviews online are a bit mixed.

“Celadrin works very well for me. I've been dealing with a shoulder injury for about six months, and I have tried almost every pain control cream and gel on the market. This is one of the best I've found,” said one reviewer.

“I'm using it on a painful knee and surrounding muscles and ligaments,” another reviewer wrote. “I was really hoping this cream would provide relief. I need to take pain pills so I can walk so I'm not sure how much this cream really helps.”

“It is truly amazing how it takes away all my aches & pains. I suffer from disc issues - cervical to lumbar area. I get referred pain in my upper arms from my cervical disc issues. I rub this on and instantly I feel so much comfort,” a woman wrote.

“Expensive. Smelly and doesn't do a thing,” said another. 

Whether it works or not, it’s fairly cheap. Celafen cream is sold online in the U.K. for £9.95 – or $11.65. You can also buy Celadrin in various formulations on Amazon for about the same price.

Study Finds Analgesic Creams Effective

Topical analgesic creams are mostly used to treat acute pain in sore muscles and joints – not the intractable pain that comes from severe chronic illness. But a new study published in the Journal of Pain Research suggests that creams are effective and could be safer than opioids and other prescription drugs in managing chronic pain.

In the observational study of 631 patients with moderately severe chronic pain, Clarity Science researchers found significant decreases in pain in patients who used generic analgesic creams daily for 3 to 6 months. Most of the creams contained diclofenac, ketoprofen or flurbiprofen, non-steroidal anti-inflammatory drugs (NSAIDS) that were combined with other neuropathic agents.

"The study is important in that existing topical analgesics that have lost big Pharma interest have been found not only to have a profound therapeutic effect, but also offer a safe and effective alternative to opioids," Dennis Harris, MD, Clarity's Chief Medical Officer said in a press release. “New and experimental drugs are not always the answer to current issues."

Researchers say 54% of treated patients in the 3-month group and 60% of treated patients in the 6-month group reduced their use of pain medications. Over half the patients who were not treated with analgesic creams increased their use of pain medication.

Treated patients also reported a preference for topical treatments and only a few had side effects.

"The results of this study show that topical analgesics were associated with reductions of up to 60% in the use of concurrent pain medications, including oral opioid analgesics,” said Jeffrey Gudin, MD, lead investigator of the study and the Director of Pain and Palliative Care at Englewood Hospital in New Jersey.

“Topical agents have the potential to provide analgesic effects without the risk of abuse, misuse, and addiction or systemic adverse events (AEs) associated with oral analgesics. Also, they lower the risk of systemic AEs and drug-drug interactions, have limited systemic absorption, offer simple-dose determination, provide direct access to the target site, and are easy for patients to apply."

For the record, Dr. Gudin was paid to participate in the Clarity Science study. Gudin is a popular speaker at pain management conferences and last year received nearly $280,000 in speaking and consulting fees from opioid manufacturers and other drug makers. Clarity Science received funding for the study from several independent specialty pharmacies that sell analgesic creams.

Lady Gaga Denies ‘Making Up’ Her Chronic Pain

By Pat Anson, Editor

Lady Gaga has postponed the European leg of her “Joanne” concert tour, announcing in an Instagram post that “trauma and chronic pain have changed my life” and would keep her from performing for several weeks.

Last week the 31-year old entertainer also canceled a concert appearance in Brazil and revealed for the first time that she suffers from fibromyalgia.

“Lady Gaga is suffering from severe physical pain that has impacted her ability to perform," tour promoter Live Nation said in a statement. "She remains under the care of expert medical professionals who recommended the postponement."

Some critics have questioned the severity of Lady Gaga’s pain, claiming she used it as an excuse to postpone her tour or as a publicity stunt to promote “Gaga: Five Foot Two,” a Netflix documentary that shows her being treated for chronic pain.

scene from "gaga: five foot two"

Lady Gaga responded to the criticism with the lengthy post on Instagram.

“As I get stronger and when I feel ready, I will tell my story in more depth, and plan to take this on strongly so I can not only raise awareness, but expand research for others who suffer as I do,” she wrote.

“I use the word ‘suffer’ not for pity, or attention, and have been disappointed to see people online suggest that I'm being dramatic, making this up, or playing the victim to get out of touring. If you knew me, you would know this couldn't be further from the truth. I'm a fighter. I use the word suffer not only because trauma and chronic pain have changed my life, but because they are keeping me from living a normal life. They are also keeping me from what I love the most in the world: performing for my fans.”

The Live Nation statement said Lady Gaga would “spend the next seven weeks proactively working with her doctors.”  

The singer's European concerts were scheduled to begin Thursday in Barcelona, Spain and run through the end of October.  Fans were told to keep their tickets until the concerts were rescheduled.  Lady Gaga is still scheduled to perform during the second leg of her North American tour, which begins November 5 in Indianapolis.

Fibromyalgia is a poorly understood disorder characterized by deep tissue pain, fatigue, depression and insomnia. As many as 90 percent of fibromyalgia cases are diagnosed in women.

Lady Gaga also has chronic hip pain from synovitis, an inflammation of the joint that can be caused by overuse or injury. Her struggle with chronic pain reportedly began over a decade ago with physical and emotional trauma caused by a sexual assault.

“I have always been honest about my physical and mental health struggles. Searching for years to get to the bottom of them. It is complicated and difficult to explain, and we are trying to figure it out,” Lady Gaga wrote on Instagram.

“I am looking forward to touring again soon, but I have to be with my doctors right now so I can be strong and perform for you all for the next 60 years or more. I love you so much.”

Researchers Question Value of Brain Imaging

By Pat Anson, Editor

An international team of researchers is recommending against the use of brain imaging as a diagnostic test for chronic pain, saying the tests are “inappropriate and unethical.”

"It's not possible at this point in time to say with any degree of certainty that a person does or does not have chronic pain based on brain imaging," said Karen Davis, PhD, senior scientist at the Krembil Research Institute and a professor at the University of Toronto.

"The only way to truly know if someone is in pain is if they tell you because pain is subjective and it is a complex experience. No brain scan can do that."

In recent years, technological advances in brain imaging have led to an increased use of functional magnetic resonance imaging (fMRI) to search for brain-based biomarkers for chronic pain.

Demand for brain imaging is also growing for legal purposes, including the development of a potential “lie detector” test for chronic pain.

"Use of such tools would be inappropriate and unethical," said Davis. "This technology is not foolproof. There are vast issues of variability between people and even within a person at different times. As a result, brain imaging must not be used as a lie detector for chronic pain."

Davis and her colleagues say brain-based biomarkers should only be used to supplement -- not replace -- a patient’s own reports of pain, even if testing is improved and valid protocols developed. Their recommendations were published in the journal Nature Review: Neurology.

"We are working towards biomarkers for chronic pain, but the goal is not as a lie detector test but rather to help provide personalized pain treatment options for patients," Davis. “People outside of the field of imaging might be disappointed, but the fact of the matter is the technology cannot be used to support or dispute a claim of chronic pain."

According to a 2015 study at the University of Michigan, one in eight visits to a doctor for a headache or migraine end up with the patient going for a brain scan. Often a doctor will order an fMRI to ease a patient’s fear that they may have a brain tumor or some other serious health problem. Doctors may also order a test to protect themselves in case of a lawsuit. About 1 to 3 percent of brain scans of patients with repeated headaches identify a cancerous growth or aneurysm.

University of Michigan researcher Brian Callaghan, MD, identified 74 neurological tests and procedures that are often unnecessary. Many involve the use of imaging.

“The two biggest areas that might be done more than they should are imaging for low back pain and imaging for headaches,” Callaghan said. “It’s a big problem and it costs a lot of money – we’re talking a billion dollars a year on just headache imaging.”

Other researchers believe brain imaging can be used as a valuable diagnostic tool. In a small study at the University of Colorado Boulder, researchers used fMRIs to discover a “brain signature” that identifies fibromyalgia with 93 percent accuracy. They found three neurological patterns in the brain that correlate with the pain hypersensitivity typically experienced with fibromyalgia.

Lady Gaga: Chronic Pain Patients Shouldn’t Feel Alone

By Pat Anson, Editor

It’s rare for a celebrity to talk openly their health problems, but Lady Gaga is speaking up about her battle with fibromyalgia and chronic hip pain. 

During a news conference at the Toronto Film Festival promoting her Netflix documentary Gaga: Five Foot Two, Lady Gaga fought back tears as she described how “liberating” it was for the film to cover her decade-long struggle with chronic pain.

“There is an element and a very strong piece of me that believes pain is a microphone. My pain does me no good unless I transform it into something that is. So I hope people watching it who do struggle with chronic pain know that they're not alone. It's freeing for me ... and I want people that struggle with it to hear me,” the 31-year old entertainer said.

“There is a degree of self-deprecation and shame with feeling in pain a lot. And I want people that watch it — that think there's no way I live (with chronic pain) because they see me dance and sing and don't think that could possibly be — to know I struggle with things like them. I work through it and it can be done. We have to stick together. I don't have to hide it because I'm afraid it's weak.”

In a teaser for the film, there are shots of Lada Gaga wincing in pain as she receives injections on a surgical table. 

"It was incredibly hard, on a basic fundamental human level, to be near someone experiencing pain like that. There's nothing you can do, beyond filming," said director Chris Moukarbel.

"I felt I needed to continue to roll. She was very aware of people struggling with similar chronic pain. She's not even sure how to deal with it.”

a scene from "GAGA: Five FOOT TWO"

“It's a part of me, and I'm grateful to Chris for caring. The compassion is overwhelming. That's why it makes me emotional. It's very touching,” Lady Gaga said.

The singer’s struggle with chronic pain reportedly began with physical and emotional trauma from a sexual assault. She later suffered a hip injury, but hid her pain from fans and her own staff until she required surgery in 2013. The singer now reportedly suffers from synovitis, an inflammation of the joint that can be caused by overuse or injury.

“I hid my injury until I couldn’t walk,” Lady Gaga told Arthritis Magazine in March. “I had a tear on the inside of my joint and huge breakage.

Lady Gaga also recently acknowledged that she has pain from fibromyalgia.

"I wish to help raise awareness & connect people who have it," she wrote in a Tweet.

"Thought ice helped #Fibromyalgia. I was wrong & making it worse. Warm/Heat is better. Electric Heated Blanket, Infrared Sauna, Epsom Baths."

Last November, Lady Gaga posted on Instagram an image of herself sitting in a sauna wrapped in an emergency blanket. Months later, she set aside her pain and soared around a stadium during a spectacular halftime show at theSuper Bowl.  

The singer told reporters in Toronto she was going to take a break from performing and  “slow down for a moment, for some healing.”  That prediction came true days later when she cancelled plans for a concert in Brazil because of severe pain.

"I was taken to the hospital its not simply hip pain or wear & tear from tour, I'm in severe pain. I'm in good hands w/ the very best doctors," she wrote on Twitter. "Brazil, I'm devastated that I'm not well enough 2 come to Rock In Rio. I would do anything 4 u but I have to take care of my body right now."

Lyrica and Neurontin Face More Scrutiny

By Pat Anson, Editor

The safety and effectiveness of Lyrica (pregabalin) and Neurontin (gabapentin) – two non-opioid drugs widely used to treat chronic pain – are drawing new scrutiny from researchers and doctors who believe the medications are over-prescribed.

In a study published in PLOS Medicine, Canadian researchers say there is little evidence that gabapentinoids – a class of nerve medication that includes Neurontin and Lyrica – are effective in treating chronic low back pain. In their review of 8 clinical studies, the researchers also found the drugs have a “significant risk of adverse effects.”

Lyrica and Neurontin are commonly prescribed for fibromyalgia and neuropathic pain, but the researchers say the drugs are increasingly prescribed for chronic back pain, even though there is “no clear rationale” for it.

"Despite their widespread use, our systematic review with meta-analysis found that there are very few randomized controlled trials that have attempted to assess the benefit of using gabapentin or pregabalin in patients of chronic low back pain," wrote lead author Harsha Shanthanna, MD, an assistant professor at McMaster University in Hamilton, Ontario.

"They necessitate prolonged use and are associated with adverse effects and increased costs. Recent guidelines from the National Health Service (NHS), England, expressed concerns on their off-label use, in addition to the risk of misuse.”

Shanthanna and his colleagues found that gabapentin showed “minimal improvement” in back pain compared to a placebo and pregabalin was “inferior” compared to other analgesics. There were no deaths or hospitalizations reported in any of the studies, but both drugs were associated with increased risk of dizziness, fatigue, visual disturbances, and diminished mental activity.

Lyrica and Neurontin are both made by Pfizer and are two of the company’s top selling drugs, generating billions of dollars in sales annually. Lyrica is approved by the FDA to treat diabetic nerve pain, fibromyalgia, post-herpetic neuralgia caused by shingles, and spinal cord injuries. It is also prescribed off-label to treat other chronic pain conditions, including lower back pain.

Neurontin is only approved by the FDA to treat epilepsy and neuropathic pain caused by shingles, but is widely prescribed off label to treat depression, ADHD, migraine, fibromyalgia and bipolar disorder. According to one estimate, over 90% of Neurontin sales are for off-label uses. Pfizer has paid $945 million in fines to resolve criminal and civil charges that it marketed Neurontin off-label to treat conditions it was not approved for.

Sales of pregabalin and gabapentin have risen steadily in recent years, in part because of CDC prescribing guidelines that recommend the two drugs as alternatives to opioid pain medication. About 64 million prescriptions were written for gabapentin in the U.S. last year, a 49% increase since 2011.

“We believe… that gabapentinoids are being prescribed excessively — partly in response to the opioid epidemic,” Christopher Goodman, MD, and Allan Brett, MD, recently wrote in a commentary published in The New England Journal of Medicine. “We suspect that clinicians who are desperate for alternatives to opioids have lowered their threshold for prescribing gabapentinoids to patients with various types of acute, subacute, and chronic noncancer pain.

“Patients who are in pain deserve empathy, understanding, time, and attention. We believe some of them may benefit from a therapeutic trial of gabapentin or pregabalin for off-label indications, and we support robust efforts to limit opioid prescribing. Nevertheless, clinicians shouldn’t assume that gabapentinoids are an effective approach for most pain syndromes or a routinely appropriate substitute for opioids.”

FDA Seeks Public Comment on Abuse of Lyrica

The U.S. Food and Drug Administration announced last week that it was seeking public comment on reports that pregabalin is being abused. The FDA action was in response to a formal notification from the World Health Organization (WHO) that it may place international restrictions on pregabalin to reduce the risk of abuse and diversion. The FDA has until September 30 to respond to WHO.

“Reports indicate that patients are self-administering higher than recommended doses to achieve euphoria, especially patients who have a history of substance abuse, particularly opioids, and psychiatric illness. While effects of excessively high doses are generally non-lethal, gabapentinoids such as pregabalin are increasingly being identified in post-mortem toxicology analyses,” the FDA said in a notice published in the Federal Register.

Pregabalin is already classified as Schedule V controlled substance in the U.S. under the Controlled Substances Act, which means the DEA considers it to have a low potential for abuse.

The idea that Lyrica and Neurontin are being abused is surprising to many patients and doctors, but there are growing signs the drugs are being used recreationally.

Both Lyrica and Neurontin have been linked to heroin overdoses in England and Wales, where prescriptions for both drugs have soared in recent years.  Addicts have apparently found the medications enhance the effects of heroin and other opioids.

A small study of urine samples from patients being treated at U.S. pain clinics and addiction treatment centers found that one in five patients were taking gabapentin without a prescription.

Gabapentin and pregabalin are also being abused by prison inmates, according to Jeffrey Keller, MD, chief medical officer of Centurion, a private corrections company. 

“Gabapentin is the single biggest problem drug of abuse in many correctional systems,” Keller recently wrote in Corrections.com. “There is little difference (in my opinion) between Lyrica and gabapentin in both use for neuropathic pain or for abuse potential.”

Pfizer did not respond to a request for comment.

Brain Scans Link Fibromyalgia and Pelvic Pain

By Pat Anson, Editor

Fibromylagia and urological pelvic pain would seem to have little in common. The former causes widespread body pain, while the latter is marked by chronic inflammatory pain in the bladder or prostate.

But researchers at the University of Michigan have stumbled upon something that both conditions share – besides being difficult to treat.

While examining MRI brain scans of over 1,000 participants enrolled in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network  -- also known as the MAPP study – they found that people with fibromyalgia or chronic urological pelvic pain both have increased “gray matter” in their brains. Gray matter is tissue in the brain that helps transfer signals between nerves.

"Interestingly, when we put these individuals into the brain imaging scanner, we found that those who had widespread pain had increased gray matter and brain connectivity within sensory and motor cortical areas, when compared to pain-free controls," says Richard Harris, PhD, an associate professor of anesthesiology and rheumatology at Michigan Medicine.

Harris and colleagues want to know if widespread pain, thought to be a marker of centralization in the nervous system, actually originates in the brain. So it was a bit of a surprise to find additional gray matter in the brains of people with urological pelvic pain, a condition that can be caused by interstitial cystitis or chronic prostatitis.

"What was surprising was these individuals with widespread pain, although they had the diagnosis of urological chronic pelvic pain, were actually identical to another chronic pain disorder: fibromyalgia," said Harris.

In addition to the MRI scans, study participants were also asked to draw on a body map where they were experiencing pain. Many of those with pelvic pain indicated they had widespread body pain.

"This study represents the fact that pelvic pain patients, a subset of them, have characteristics of fibromyalgia," Harris says. "Not only do they have widespread pain, but also they have brain markers indistinguishable from fibromyalgia patients."

Harris hopes the study will lead to new ways of treating chronic pain -- as there might be similarities across pain conditions if both show widespread pain.

"We think that this type of study will help treat these patients because if they have a central nerve biological component to their disorder, they're much more likely to benefit from targets that affect the central nervous system rather than from treatments that are aimed at the pelvic region," Harris said.

Insurance Claims Climb for Lyme Disease

By Pat Anson, Editor

Private insurance claims with a diagnosis of Lyme disease have soared in the U.S. over the past decade, according to a new report by FAIR Health, a nonprofit that tracks healthcare costs and insurance trends.

Lyme disease is a bacterial illness spread by ticks. It can also lead to other chronic pain conditions such as joint and back pain, chronic fatigue, fibromyalgia and neuropathy.

Fair Health analyzed a database of 23 billion private insurance claims from 2007 to 2016, and found that claims with a diagnosis of Lyme disease increased by 185 percent in rural areas and 40 percent in urban areas.

A recent CDC study also found the number of Lyme disease cases increasing, with nearly 40,000 confirmed and probable cases in 2015.

"Lyme disease is growing as a public health concern,” said FAIR Health President Robin Gelburd

Although Lyme disease historically has been concentrated in the Northeast and upper Midwest, the FAIR Health study suggests that it is spreading geographically. In 2007, insurance claims with diagnoses of Lyme disease were highest in New Jersey, Rhode Island, Connecticut, Massachusetts and New York.

By 2016, the top states were Rhode Island, New Jersey, Connecticut, North Carolina and New York -- with the emergence of North Carolina suggesting significant expansion to a new region.

Summer is the peak season for Lyme disease, with insurance claims more common in rural than in urban settings, according to the FAIR Health report. In the winter and early spring (December through April), claims involving Lyme disease were reported more often in urban than rural settings.

Age is also a differing factor in rural and urban environments. In rural settings, claims with Lyme disease diagnoses were more common for middle-aged and older people. Patients aged 41 years and older accounted for nearly two-thirds of the rural diagnoses. In urban populations, younger individuals with Lyme disease accounted for a higher percentage of claims.

Lyme disease is usually treated with antibiotics, but some patients experience complications that lead to Lyme disease syndrome (PTLDS), with long-term symptoms such as fatigue, muscle and joint pain and cognitive issues. Autoimmune diseases have also been associated with chronic Lyme disease.

Left untreated, Lyme disease can lead to serious chronic conditions, as Sarah Elizabeth Hirschle shared with us recently.

For patients with a Lyme disease diagnosis, FAIR Health reported the most common subsequent diagnoses were:

• Joint pain (dorsalgia, low back pain, hip and knee pain)
• Chronic fatigue  
• Soft tissue disorders (myalgia, neuralgia, fibromyalgia)
• Hypothyroidism

lyme disease rash

Early symptoms of Lyme disease include fever, chills, headaches, fatigue, muscle and joint aches, and swollen lymph nodes. A delayed rash often appears at the site of the tick bite. The rash grows in size and sometimes resembles a bulls-eye.

The Link Between Chronic Pain and Depression

By Lana Barhum, Columnist

There are nearly 40 million American adults living with severe or significant chronic pain, according to the National Institutes of Health. Chronic pain affects more people than cancer, diabetes and heart disease combined.   

Chronic pain is devastating and can be a challenge to treat. Pain also causes depression and depression leads to decreased function, poor treatment outcomes and further healthcare costs. About half of people with chronic pain are also depressed, according to a recent study in the Journal of Affective Disorders.

"The dual burden of chronic physical conditions and mood and anxiety disorders is a significant and growing problem," wrote senior author Silvia Martins, MD, associate professor of Epidemiology at the Mailman School of Public Health.

Pain experiences are different for each person and your response to chronic pain depends on how you feel pain, and thoughts and behaviors related to your underlying pain conditions.  

When pain invades every aspect of your life and leaves you uncertain of the future, anxiety, sadness, anger and grief are imminent. For many, the burden is so difficult, it leads to major depressive disorder, also known as clinical depression.

Research shows the highest rates of clinical depression are in people with fibromyalgia. According to a study in Pain Research and Treatment, people with fibromyalgia have a 90% chance for depressed symptoms and up to 86% risk for major depressive disorder. 

What is Clinical Depression?

Clinical depression is more complicated than dealing with sadness and grief. This type of depression leaves you unable to focus on work, get good quality sleep, eat well, or enjoy time with friends and loved ones.  Some people experience clinical depression once, but many have experienced it several times during their life.

Some symptoms of clinical depression are:

• Fatigue and loss of energy
• Feelings of guilt and worthlessness
• Struggles with concentration and decision making
• Sleep problems, including insomnia or excessive sleeping
• Disinterest in almost all activities
• Constant thoughts of dying and suicide
• Significant weight loss or gain

My Experience with Clinical Depression

Depression has been a frequent visitor to my chronically painful life, but the first time I was formally diagnosed with clinical depression was 2011.  It had been 3 years since I was diagnosed with rheumatoid arthritis and fibromyalgia, two painful and life-altering conditions.  Not only was pain dominating my life, there was so much more happening because of pain, that I couldn’t handle it all. 

I knew I was struggling, but I didn’t know the extent.  I was crying for no reason, not sleeping, and my mind was constantly racing.  And I thought about death – not contemplating suicide but that death had to be better than living with real physical and emotional pain.

It was my rheumatologist who recognized the extent of my depression, prescribed an anti-depressant and referred me to a therapist. Talk therapy helped me better handle my feelings about living with pain and other obstacles, and the medication managed the chemical part of depression. Eventually and with time, I found some clarity.

There have been other times in more than nine years of living with illness and pain that depression has gotten its clutches on me. But it was not until last summer that I had another episode of clinical depression.  I unexpectedly lost my mother in late August and that loss shook me to my very core and brought back my old friend depression with it.

Preventing Recurrent Depression

Anyone who has suffered from at least one episode of depression is at risk for another, and the risk is higher in people who have been diagnosed with clinical depression. According to a 2104 report from the University Medical Center Groningen in The Netherlands, recurrent depression is more common in people who live with pain.

The best way to treat and prevent recurrent depression, according to a discussion in the Primary Care Companion to The Journal of Clinical Psychiatry, is through maintenance therapy that includes talk therapy and medication, and where medication is decreased as the depression lessens.

Depression does not have to last forever and it doesn’t have to consume your life. But when you are dealing with the sadness, anger, grief and pain, relief seems unimaginable.  My experience with clinical recurrent depression and pain has taught me that there is always hope.  It won’t be easy, but it’s not impossible.

If you want to manage your depression and prevent it from coming back, it is important to take a proactive approach.  Here’s how:

Early Recognition. If you have been clinically depressed before, you know that depression comes and goes.  If you find you are feeling exhausted, hopeless, distressed and struggling to be productive daily, reach out to your doctor or therapist to find ways to keep symptoms from worsening.  

Learn Your Triggers. For most of us, pain is a stressor and increases the chance being depressed.  But depressed feelings and anxiety also worsen pain. Therefore, it’s important to focus on minimizing things that exacerbate pain.

Communication.  Many people with chronic pain do not reach out to their doctors because they don’t think there is anything that can be done or they feel that if their pain levels are managed, then their depression will go away. But depression doesn’t just go away and it only worsens your pain levels.  Getting treatment is the only way to a full recovery and to prevent depression from returning.

Please know you are not alone.  There are millions of people with chronic pain and clinical recurrent depression. Reach out and seek support, whether it is online, in a local community support group or from others – a pastor, a mental health professional, a friend or loved one.   Your mental health is just as important as your physical and it is important to treat it as such.

Can Vitamin D and Good Sleep Reduce Pain?

By Pat Anson, Editor

Vitamin D supplements, along with good sleeping habits, could help manage chronic pain from fibromyalgia, rheumatoid arthritis, back pain and other conditions, according to a new study.

The importance of vitamin D – the “sunshine vitamin” – in maintaining bone strength and overall health has long been known.  But recent research has focused on the role it plays in inflammation, musculoskeletal pain and sleep disorders.

“Vitamin D status seems to have an important role in the bidirectional relationship observed between sleep and pain,” said senior author Dr. Monica Levy Andersen in the Journal of Endocrinology. “We can hypothesize that suitable vitamin D supplementation combined with sleep hygiene may optimize the therapeutic management of pain-related diseases, such as fibromyalgia."

Andersen and her colleagues at Universidade Federal de Sao Paulo in Brazil reviewed 35 clinical studies of vitamin D, and concluded that vitamin D supplements could increase the effectiveness of pain treatments by stimulating an anti-inflammatory response.

"This research is very exciting and novel. We are unraveling the possible mechanisms of how vitamin D is involved in many complex processes, including what this review shows - that a good night's sleep and normal levels of vitamin D could be an effective way to manage pain," said Sof Andrikopoulos, assistant professor at the University of Melbourne and Editor of the Journal of Endocrinology.

Sources of Vitamin D include oily fish and eggs, but it can be difficult to get enough through diet alone. Ultraviolet rays in sunlight are a principal source of Vitamin D for most people.

Several recent studies have found an association between chronic pain and low levels of Vitamin D in the blood.  Researchers at National Taiwan University Hospital found low levels of serum vitamin D in over 1,800 fibromyalgia patients. Danish researchers have also found an association between lack of sunlight and multiple sclerosis.

But some question quality of the studies and whether Vitamin D supplements do any good.

“Evidence does not support vitamin D supplementation for the treatment of multiple sclerosis and rheumatoid arthritis or for improving depression/mental well-being,” wrote Michael Allan, a professor of Family Medicine and director of Evidence Based Medicine at the University of Alberta in the Journal of General Internal Medicine.

Allan says much of the research is of low quality. He doesn’t dispute the overall health benefits of Vitamin D – such as building strong bones and teeth -- but thinks taking supplements is unnecessary and could even be harmful in large doses.

"The 40 year old person is highly unlikely to benefit from vitamin D," said Allan. "And when I say highly unlikely, I mean it's not measurable in present science."
