Rheumatoid arthritis (RA) is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition can damage a wide variety of body systems, including the skin, eyes, lungs, heart, and blood vessels. An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body’s tissues.
Rheumatoid arthritis, or RA, is an autoimmune and inflammatory disease, which means that your immune system attacks healthy cells in your body by mistake, causing inflammation (painful swelling) in the affected parts of the body. RA mainly attacks the joints, usually many joints at once. RA commonly affects joints in the hands, wrists, and knees.
Rheumatoid arthritis (RA) causes joint inflammation and pain. It happens when the immune system doesn’t work properly and attacks the lining of the joints, called the synovium. The disease commonly affects the hands, knees, or ankles, and usually the same joint on both sides of the body, such as both hands or both knees.
