More Americans Have Chronic Pain Than Ever Before

By Pat Anson

Rates of chronic pain and high-impact pain have risen sharply in the United States since the start of the COVID-19 pandemic, which is likely due to an increase in sedentary lifestyles, anxiety and reduced access to healthcare.

In a study preprinted in medRxiv, researchers estimate that 60 million Americans in 2023 had chronic pain, up from 50 million in 2019. The study is based on results from 2019, 2021 and 2023 National Health Interview Surveys (NHIS) of a nationally representative sample of about 88,500 U.S. adults.

Caution is warranted when research is preprinted before undergoing peer-review, but the findings here are startling. Rates of chronic pain (CP) rose from 20.6% in 2019 (before the pandemic), to 20.9% in 2021, and surged to 24.3% in 2023.

High impact chronic pain (HICP), which is pain strong enough to limit daily life and work activity, rose from 7.5% of adults in 2019 to 8.5% in 2023. That translates to 21 million Americans living with debilitating pain.

“Chronic pain and high-impact chronic pain surged dramatically after the COVID pandemic. The widely-cited 20% prevalence of CP in the adult US population appears obsolete,” wrote co-authors Anna Zajacova, PhD, at Western University in Ontario and Hanna Grol-Prokopczyk, PhD, at the University of Buffalo.

“Our findings indicated that chronic pain, already a widespread issue, has reached new heights in the post-pandemic era, necessitating urgent attention and intervention strategies to address and alleviate this growing health crisis.”

The increases in pain occurred in almost all body areas, such as the head, abdomen, back, arms, hands, hips, knees and feet, except for jaw and dental pain. All age groups and both sexes were affected.

Researchers say being infected with COVID or having long COVID played a significant role in the increases, but social and economic causes may have also been at work. Pain could have worsened due to anxiety, depression, loneliness, physical inactivity and reduced access to health care, as well as inflation and economic hardships caused by the pandemic.

“The 2023 surge is not restricted to specific demographics or body sites — it is widespread across the population subgroups and affects all examined pain sites except jaw/dental pain. Further, the increase persisted even after accounting for potential drivers such as COVID-19 infections, socioeconomic factors, and other potentially important covariates such as mental health or health behaviors. This suggests that a broader, more complex set of factors may be at play,” researchers reported.

“Thus, while the viral infections certainly had an impact, other societal and lifestyle changes that occurred during and after the pandemic may have contributed to the increase in pain. The role of increased social isolation and loneliness, disrupted health care access, and heightened levels of stress and anxiety, all of which were exacerbated by the pandemic, should be explored in future research.”

Although chronic pain rates have surged over the last few years, there has been little response from healthcare providers and regulators. In fact, the just opposite happening. The Food and Drug Administration predicted a 7.9% decline in medical need for opioid pain medication in 2024, and anticipates a 6.6% decrease in demand next year.

The Drug Enforcement Administration uses those FDA estimates when setting its annual production quotas for opioids, which have fallen for eight straight years. Since 2015, the supply of oxycodone has been reduced by over 68% and hydrocodone by nearly 73%.

Many pain patients feel like they’ve been abandoned by the healthcare system, according to a 2023 PNN survey of nearly 3,000 patients or caregivers. About one in five patients have been unable to find a doctor to treat their pain, and 12% say they were abandoned or discharged by a doctor. Many are now hoarding opioid medication or turning to other substances for relief.

Those findings from our survey are now being reflected in the study on rising pain rates.

“The findings are a call to action for public health professionals, policymakers, and researchers to further investigate the root causes of this increase. Addressing the rise in chronic pain is critical, as pain serves as a sensitive barometer of population health and has profound economic, social, and health consequences,” said Zajacova and Hanna Grol-Prokopczyk.
