More Americans Than Ever Suffer from Chronic Pain

More Americans than ever are hurting with enduring, life-restricting pain. Like obesity, this condition is on the rise, according to figures in a new NCHS Data Brief from the Center for Disease Control and Prevention (CDC).

In 2023, 24.3% of US adults had chronic pain, and 8.5% had high-impact chronic pain (HICP) that frequently limited daily activities in the past 3 months. Both types increased with age and with decreasing urbanization level. Women were more likely than men to have HICP (23.2% vs 7.3%). 

Like obesity, chronic pain is multifactorial and is best managed with multidisciplinary intervention, said Jianguo Cheng, MD, PhD, a professor of anesthesiology and medical director of the Cleveland Clinic Consortium for Pain, Cleveland, Ohio. “It’s a complex mix of genetic, biological, and psychosocial dimensions that can cause ongoing pain out of proportion to the original limited injury that triggered it.”

While today’s longer lifespans are the primary driver of the increase, noted Martin Cheatle, PhD, an associate professor of psychiatry, anesthesiology, and critical care and director of behavioral medicine at the Penn Pain Medicine Center at the University of Pennsylvania’s Perelman School of Medicine, Philadelphia, another important factor is the more than 100 million Americans who suffer from obesity. “Obesity is a major risk factor for chronic pain conditions including advancing joint disease, low back pain, and diabetic neuropathies,” he said.

Age is an amplifier, agreed Beth Darnall, PhD, a professor of anesthesiology and perioperative and pain medicine and director of the Pain Relief Innovations Lab at Stanford University in Palo Alto, California, but the increases in chronic pain and HICP cut across age strata. 

“Across the board we see striking increases in chronic pain, such as a 5% increase for those 65 and older, and a nearly 2% increase in HICP in that same age group,” Darnall said, referencing the changes from 2019 data in the new NCHS Data Brief. “And an almost 4% increase was observed for the youngest adult age category,18 to 29. Some of our research is now focusing on how to best treat chronic pain in young adults.”

The rise in chronic pain is broadly linked to the overall decline in the health of the US population, as indicated by the CDC 2024’s Chronic Disease Prevalence in the US: Sociodemographic and Geographic Variations by Zip Code Tabulation Area.

The Opioid Crisis and COVID

Beginning in 2016, in response to the opioid crisis and CDC guidelines, opioid prescribing for chronic pain rapidly dropped, both in terms of new prescriptions and tapering of doses of long-term users. “Reduced opioid prescribing yielded benefits for some patients but created new problems and harms for other patients,” said Darnall. Cheng added that the CDC’s recommendations on opioid prescribing were widely misinterpreted and were applied to patients with painful conditions such as cancer and sickle cell disease who were not intended to be affected by the guidelines. “In addition, although medical opioid prescribing dropped by 50%, overdose deaths from non-medical opioid sources increased by more 50%.”

Currently, most opioid overdoses are related to heroin, fentanyl, and newer drugs of abuse such as xylazine. “Most pain clinicians would agree that opioids are not first-line therapy for chronic non-cancer pain, but in a select number of well-vetted patients, opioids can be very effective in improving functionality and quality of life as part of a multimodal approach to pain care,” Cheatle said. 

The impact of the opioid crisis is complex, said Cheatle, noting that only 8%-10% of pain patients on long-term opioid therapy develop a use disorder. “However, opioids were overly prescribed due to clinicians’ lack of training in core competencies of pain management and the insurance companies’ refusal to adequately cover non-opioid therapies such as acupuncture, cognitive behavioral therapy, extended physical therapy, and medical massage,” he said. 

He pointed out that in the late 1990s there were more than 1000 multidisciplinary pain centers, whereas currently there are many fewer owing to lack of insurance reimbursement. “This results in more possibly avoidable invasive surgeries, which can further contribute to the increase in chronic pain.” 

The COVID pandemic further exacerbated the pain problem and delayed access to timely medical interventions for many people. Some adopted a more sedentary lifestyle, already entrenched in today’s technology-driven society, leading in turn to weight gain and more chronic pain. “The isolation and lack of normal human connections during the pandemic could exacerbate pain and loss of autonomy,” Cheatle said. And some individuals developed painful neurologic conditions related to long-haul COVID, for which there is no effective treatment. 

Best Approach

“Historically, pain has been treated as a purely biomedical issue. Bringing a biopsychosocial perspective to pain care can support pain relief,” said Darnall. Multiple national clinical guidance documents have called for a comprehensive approach that considers the whole person: their circumstances, their needs, their stressors, and their environment. “And we must provide patients meaningful access to the lowest-risk, non-pharmacologic treatments first – and ideally early on,” she said.

Even effective medications rarely make a person pain free, so other approaches are needed in tandem, Darnall said. Support for stronger patient competency in self-management of chronic pain is mounting.

“It’s vitally important that we help people know how to help themselves have less pain – how to steer their mind and body toward relief by using pain relief skills,” she said. “By so doing they can cultivate a critical level of control over their pain and are less at its mercy, which supports good mood and is shown to help people be more active as the impacts of pain diminish.”

Darnall outlined a recent development in the primary care setting that involves offering patients a brief program in pain-relief skills training. Within Veterans Affairs primary care, for example, patients receive several 30-minute sessions in pain reduction techniques. Outside of the VA, primary care clinics are incorporating an evidence-based, one-session 2-hour pain relief skills class called Empowered Relief, as standard care. 

The class teaches participants three pain management skills and creates a personalized plan for each that includes a free app for ongoing daily use.

Since pain causes agitation in the central nervous system, manifested as fast heart rate, rapid breathing, muscle tension, and distress, people learn various ways to calm the central nervous system – with, for example, a sound technology known as binaural audio to deepen the relaxation response. “They also learn to identify and target worry about pain and develop self-soothing actions to interrupt unhelpful patterns,” Darnall said. 

Data from randomized chronic pain studies, including one by her group using a virtual reality training program for lower back pain, show that 3 months after the training program people report clinically meaningful reductions in pain intensity, pain interference with daily activities, and sleep disturbance, as well as pain-related distress, anxiety, and fatigue

While psychological and complementary approaches have been effective in improving function and mood, there are barriers to accessing them, said Cheatle, such as lack of insurance coverage and the stigma associated with non-traditional, especially psychological, care.

Prevention

Good lifestyle behaviors promote better health as people age. “Maintaining a healthy weight, staying active, prioritizing good sleep, and avoiding smoking and alcohol use can support better health and buffer against chronic diseases and pain,” Darnall said. Cheatle noted the importance of maintaining a safe work environment and avoiding injury risks by, for example, wearing a seatbelt or a cycling helmet. 

The Future 

“We need to ensure all individuals have access to effective, low-burden pain treatments, including evidence-based treatments they can receive from home so as to minimize treatment disparities.” Darnall said. Also needed is better comprehensive treatment for acute and chronic pain alike. “If we treat acute pain better, we will have fewer people transitioning to the chronic pain state,” she said.

To that end, added Cheng, healthcare professionals in every specialty from doctors and nurses to psychologists and chiropractors need to develop co-competencies in pain management. 

For Cheatle, the near future looks bleak. “There are some pioneering bioengineering approaches to reduce chronic pain and novel pharmacologic agents such as calcitonin gene-related peptide inhibitors for intractable migraines, but just changing insurance reimbursement for a comprehensive approach to chronic pain care and bolstering healthcare provider education on core pain competencies will benefit the over 50 million adults who suffer from chronic pain.” 

Cheng, however, is more sanguine. “I don’t expect miracles in 10 years’ time, but we’re making rapid progress in understanding the genetics of chronic pain and the mechanisms of disease and therapy. We’re developing biomarkers to help in prognosis and monitor disease progress.” In the meantime, he pointed to an expanding array of non-pharmaceutical options, including neuromodulatory approaches such as nerve blocks and spinal cord stimulation.

Cheng, Cheatle, and Darnall disclosed no relevant competing interests.
