Beyond Inflammation: Chronic Rheumatic Pain as a Stable Pathological Functional System
The contemporary discussion of chronic rheumatic pain has begun to move beyond a narrow inflammatory model. Recent reporting from EULAR 2026 emphasized that a substantial proportion of patients continue to experience severe or unacceptable pain years after diagnosis, even in the context of anti-inflammatory treatment, and proposed several important contributors to this persistent burden, including nociplastic pain, poor sleep, psychological distress, and kinesiophobia. This shift is important because it recognizes that pain persistence cannot always be explained by active inflammation alone. Yet the findings may support an even deeper interpretation. Rather than viewing these variables as separate complicating factors layered onto inflammatory disease, it may be more accurate to understand them as elements of a unified pathological organization. In this view, chronic rheumatic pain can evolve into a relatively stable pathological functional system, one in which altered nociceptive...
