Why a Flare Looks the Way It Does
Rheumatoid arthritis (RA) is an immune mediated disease in which inflammation targets the synovium, the tissue lining a joint.
Rheumatoid arthritis (RA) is an immune-mediated disease in which inflammation targets the synovium, the tissue lining a joint. During a flare, synovial inflammation increases: the joint becomes swollen, warm, tender, and less mobile, while inflammatory symptoms such as fatigue and prolonged morning stiffness intensify. Persistent inflammation can damage cartilage and bone, so a flare is not simply a temporary increase in pain. The pattern often involves several joints, particularly the hands, wrists, and feet, with relatively symmetrical symptoms. Morning stiffness occurs because inflamed joints become more painful and restricted after inactivity. The nurse notices not only the pain score but also whether the patient can make a fist, button clothing, walk, prepare food, or perform other tasks that were previously manageable. Function often reveals a meaningful change before a laboratory result returns. Immunomodulators target the inflammatory process rather than providing immediate analgesia. Conventional synthetic DMARDs such as methotrexate reduce disease activity over time; biologic and targeted synthetic DMARDs act through more specific immune pathways. Glucocorticoids work faster, which is why they may be used briefly as a bridge while a...
