Rheumatoid Arthritis (RA) Signs & Symptoms (& Associated Complications)

This lesson covers rheumatoid arthritis, a chronic autoimmune condition characterized by inflammatory polyarthritis and extra-articular manifestations. It affects about 1% of the population, predominantly women aged 35-50. Key signs include morning stiffness, joint swelling, and pain that improves with activity. Rheumatoid arthritis typically affects small joints symmetrically, sparing the DIP joints. Common deformities include swan-neck and Boutonniere. Systemic symptoms like fatigue, fever, and weight loss may precede joint symptoms. Extra-articular manifestations include nodules, scleritis, and lung issues.
