Controlling inflammation isn't always enough to control pain in rheumatoid arthritis. A large Swedish study found that 1 in 4 early RA patients still reported unacceptable pain at 2 years despite having low inflammation levels. Women and those with more tender than swollen joints at diagnosis were at the highest risk.
Treating inflammation in rheumatoid arthritis (RA) is the cornerstone of care — but a new study suggests that for many patients, getting inflammation under control doesn't mean getting pain under control. Researchers analyzed data from over 10,000 Swedish patients newly diagnosed with RA and found that a significant portion continued to experience unacceptable pain two years in, even when their inflammatory markers were low.
The study, published in Annals of the Rheumatic Diseases, found that women were disproportionately affected, facing up to 56% higher odds of persistent pain despite low inflammation compared to men. Patients who started with higher baseline pain scores or had notably more tender joints than swollen ones were also more likely to remain in pain long-term — suggesting that non-inflammatory mechanisms may be contributing.
By the Numbers:
Why it matters: These findings challenge the assumption that suppressing inflammation is sufficient for RA pain management. Clinicians may need to look beyond CRP levels and joint swelling — especially in female patients — to identify those at risk for chronic pain and tailor treatment accordingly.
