About one-third of people with rheumatoid arthritis (RA) continue to report unacceptable pain 15 years after diagnosis, despite receiving anti-inflammatory treatment. This troubling finding challenges the long-held assumption that suppressing inflammation automatically resolves pain, and it's prompting rheumatologists to rethink how they approach chronic pain management.

What Happens When Inflammation Control Isn't Enough?

For decades, rheumatology has operated on a straightforward principle: reduce inflammation, and pain disappears. But research presented at the European Alliance of Associations for Rheumatology (EULAR) 2026 Annual Meeting reveals a far more complex picture. Pain isn't simply a marker of active inflammation; it's a highly processed signal shaped by biological, psychological, and social factors working together.

One key discovery is the prevalence of what researchers call "nociplastic pain," which refers to altered pain processing in the nervous system that causes hypersensitivity even when there's no clear tissue or nerve damage. Fibromyalgia, a condition characterized by widespread musculoskeletal pain and fatigue, is the prototypical example. Remarkably, fibromyalgia affects about 21% of people with RA, nearly 10 times higher than in the general population.

A systematic review tracking over 13,000 patients found that up to 42% reported distinct pain sensitization, which was significantly associated with worse reported disease activity, profound disability, lower quality of life, and low mood. Even more striking, about 20% to 30% of people show features of centrally mediated pain already at the time of diagnosis, not just after years of chronic disease.

How Does Sleep Disruption Drive Persistent Pain?

Among the modifiable factors that influence chronic pain, sleep emerges as one of the most powerful. Sleep disturbances are pervasive in RA: insomnia affects 63% to 73% of patients, while obstructive sleep apnea can affect up to 64% of patients, depending on how it's measured.

The relationship between sleep and pain is bidirectional. While it's intuitive that joint pain disrupts sleep, the reverse is equally true: sleep deprivation directly induces pain hypersensitivity. Research from the Canadian Early Arthritis Cohort tracked over 1,000 patients with newly diagnosed RA to identify which baseline factors predicted persistent unacceptable pain 12 months later. While baseline pain intensity was a predictor, sleep problems were also significantly and independently predictive of persistent pain in a clear dose-response relationship.

"Sleep problems are not just a consequence of pain; they can lead to increased pain sensitivity and greater and more widespread pain," explained Yvonne Lee, MD, a professor of medicine and rheumatologist at Northwestern University Feinberg School of Medicine.

Using objective wrist actigraphy (a device that measures sleep patterns), researchers found that wake after sleep onset and low sleep efficiency directly correlate with higher temporal summation of pain, meaning the nervous system becomes increasingly sensitized to pain signals.

How to Address Sleep and Pain Together

• Optimize sleep-disrupting medications: Systematically taper down glucocorticoids such as prednisone to under 7.5 mg daily, as these medications can significantly disrupt sleep quality and contribute to pain sensitivity.
• Use cognitive-behavioral therapy for insomnia: This evidence-based approach utilizes behavioral strategies such as sleep restriction and stimulus control, with digital apps available if local specialists are unavailable.
• Practice good sleep hygiene: Aim for a consistent bedtime and wake time, unplug from screens an hour before bed, and use blackout curtains to keep bright light from entering your bedroom while sleeping.
• Treat concurrent depression: Depression and sleep problems often occur together and can amplify pain sensitivity, so addressing both conditions may help break the pain cycle.

What Role Does Fear of Movement Play in Chronic Pain?

Another major barrier to pain management is kinesiophobia, an irrational and debilitating fear of physical movement rooted in the belief that motion will cause pain or reinjury. This psychological factor is particularly prominent in axial spondyloarthritis (axSpA), a type of inflammatory arthritis affecting the spine and pelvis.

When patients experience pain upon moving, they instinctively stop. This physical inactivity triggers a cascade of harmful effects: a positive energy balance, accumulation of visceral fat, and infiltration of macrophages into adipose tissue, which then secrete proinflammatory cytokines that compound the systemic inflammation already driving the arthritis.

"From a physiotherapist's perspective, the mother of all evil is actually kinesiophobia," stated Deniz Bayraktar, a physiotherapist and researcher at the University of Iceland.

Clinicians frequently misinterpret these deep-seated fears as simple reluctance or nonadherence. However, persistent pain might not be inflammatory but neuropathic or nociplastic, requiring a different approach. Simply telling a fearful patient to exercise is rarely effective; instead, clinicians must use complementary strategies to lower the barrier to movement, such as gamification, virtual reality, or shifting to an inherently safer environment like a heated pool for aquatic therapy.

What About Fibromyalgia Flares and Environmental Triggers?

For people with fibromyalgia, understanding personal triggers can help manage unpredictable symptom flares. Many people report that pain and stiffness worsen during changes in temperature or barometric pressure. Seasonal transitions, such as the shift into spring and fall, can be particularly challenging because temperatures fluctuate more frequently between warm and cool.

Beyond weather, sensory sensitivity plays a significant role. People with fibromyalgia often experience hypervigilance, manifesting as heightened sensitivity to noise, clutter, bright lights, or strong scents. This sensory overload can trigger or worsen symptoms.

Research on diet and fibromyalgia is emerging and mixed, and there's no science-backed "fibromyalgia diet" proven to work for everyone. Instead, some people might notice certain foods seem to worsen their symptoms, so tracking dietary patterns can help identify personal triggers.

How Can You Identify Your Personal Pain Patterns?

Keeping a detailed journal can help you recognize connections between daily habits and symptom changes. Rather than relying on memory, track specific factors over time to identify patterns.

• Sleep quality and duration: Record how many hours you sleep and how rested you feel upon waking, as sleep is one of the strongest triggers of fibromyalgia symptoms.
• Stress levels and emotional state: Note daily stress and mood, since psychological distress strongly predicts long-term persistent pain.
• Physical activity and pacing: Track exercise type, duration, and intensity, as well as how you feel afterward, to identify the "boom-and-bust" cycle where overactivity leads to flares.
• Environmental factors: Record weather changes, temperature, humidity, noise levels, and other sensory exposures that coincide with symptom changes.
• Dietary habits: Note what you eat and any symptom changes that follow, since some people notice certain foods worsen their symptoms.

However, it's equally important to flip the question around. Instead of only focusing on what worsened symptoms, pay attention to what happens on days when you feel better. "What made it such a good day? Can you identify the factors that really gave you a better day rather than what made it bad?" suggests Mary Ann Fitzcharles, MD, an associate professor of medicine in the division of rheumatology at McGill University.

"Most people don't have to catalog and say, 'I don't know which one it is.' They know if they can't handle cold weather, or if too much noise going to a busy social gathering might be an issue," noted Fitzcharles.

At times, there may not be any rhyme or reason for symptoms. It's not unusual for patients to report a few good days followed by a bad day they can't attribute to anything specific.

The Shift Toward Comprehensive Pain Management

The non-opioid pain treatment market is expanding rapidly, expected to grow from $41.69 billion in 2024 to $90.84 billion by 2034, reflecting a broader shift in how healthcare providers approach pain management. This growth is driven by increasing awareness of the risks associated with opioid dependence and a growing focus on safer, more comprehensive pain management alternatives.

Non-opioid pain treatments include a broad range of approaches such as nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, local anesthetics, nerve blocks, physical therapy, rehabilitation programs, and innovative non-opioid pharmaceuticals. These therapies are designed to alleviate pain by targeting specific biological pathways without activating opioid receptors.

Emerging trends in pain management include increased focus on personalized medicine, where treatments are tailored based on patient age, medical history, and condition severity. Non-drug therapies such as physical therapy, acupuncture, cognitive-behavioral therapy (CBT), and transcutaneous electrical nerve stimulation (TENS) are gaining strong adoption and are often combined with non-opioid medications to provide holistic, safer, and long-term relief for chronic conditions such as fibromyalgia, arthritis, and back pain.

The key takeaway for patients is clear: if you're experiencing persistent pain despite anti-inflammatory treatment, the problem may not be inflammation alone. Sleep quality, psychological factors like fear of movement, and nervous system sensitization all play significant roles. Working with your healthcare provider to address these underlying drivers, rather than simply escalating medication doses, may offer better long-term relief and improved quality of life.
