Most Chronic Pain Conditions Never Get Better

By Crystal Lindell

Most chronic pain conditions remain stable over time, with few patients getting worse and even fewer getting better. 

That’s according to a new study in JAMA Network Open that tracked over 1,477 patients with long-term non-cancer pain. The patients were being treated at specialized pain clinics in France.

The researchers used a cell phone app to track patients’ self-reported bodily comfort, sleep, and mood every week for six months. They excluded “pain intensity” from the list of things they tracked because it is "increasingly recognized as an incomplete proxy for the chronic pain experience.”

Most of the participants were middle-aged, overweight, professional women. About a fifth were on sick leave due to pain. 

Most had been dealing with pain for over five years, mainly from conditions like fibromyalgia and musculoskeletal pain. A large majority had a history of other medical conditions, including anxiety, depression and substance use disorders.

The primary medications that patients took were antidepressants, paracetamol (acetaminophen) and antiepileptic drugs; while the main nonpharmacological treatments were neuromodulation and physical therapy. 

The study authors were trying to find ways to predict which patients would improve and which ones may get worse. They hoped to use responses to basic questions at the start of the study, such as age, sex, pain severity and medical history, to help develop models that would predict how patients would fare.

Unexpectedly, most of the patients remained the same throughout the course of the study, with bodily comfort, sleep and mood remaining unchanged. Only 4.1% of patients improved, and just 10.2% got worse.

Researchers concluded that the most realistic outcome for the remaining 85% is to keep them stable. 

"These findings suggest that chronic pain… is better conceptualized as a stable digital state with rare transitions,” the researchers said. “In tertiary care, where patients are referred precisely because prior treatments have failed, preventing further deterioration over 6 months represents a meaningful therapeutic achievement.” 

Ideally, this type of research could be used to help doctors more realistically assess and treat chronic pain. For example, if their chronic pain is stable, patients shouldn’t have to see a pain specialist every four weeks to get their prescriptions renewed. And treatments should focus on keeping patients comfortable.

Sadly though, the results also suggest that most chronic pain conditions are never really cured or get better, even when treated at a specialized pain clinic.

My hope is that we will continue to find treatments and therapies that meaningfully improve chronic pain. After all, in an ideal world, chronic pain would not remain stable – it would go away.
