Rheumatoid Arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints. Unlike the wear-and-tear damage of osteoarthritis, RA affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. It can affect more than just your joints, potentially causing numerous medical issues in various parts of the body.

The most common areas impacted by RA include the hands, wrists, and knees. The inflammation caused by RA can damage other parts of the body as well. Early and aggressive treatment is recommended to ultimately control the disease and to prevent complications associated with RA.
