arthritis (RA) is a chronic inflammatory disorder that affects the joints, causing pain, swelling, stiffness, and potentially joint deformity. It is an autoimmune condition where the immune system mistakenly attacks the joints, leading to inflammation and damage. RA can also affect other parts of the body, such as the skin, eyes, heart, and lungs. Treatment typically involves medications to reduce inflammation and slow the progression of the disease, as well as physical therapy and lifestyle changes to manage symptoms and improve quality of life.
