Rheumatoid arthritis (RA) is an autoimmune disease that causes inflammation of the joints. Because many symptoms of RA are similar to those of a variety of other diseases, diagnosis can be difficult. A correct diagnosis requires clinical evaluation, X-rays, and a series of laboratory tests.
Arthritis. Arthritis is a general term for conditions that affect the joints and surrounding tissues. Joints are places in the body where bones come together, such as the knees, wrists, fingers, toes, and hips. The two most common types of arthritis are osteoarthritis and rheumatoid arthritis.1  Osteoarthritis (OA) is a painful, degenerative joint disease that often involves the hips, knees, neck, lower back, or small joints of the hands. Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that usually involves various joints in the fingers, thumbs, wrists, elbows, shoulders, knees, feet, and ankles. 2  An autoimmune disease is one in which the body releases enzymes that attack its own healthy tissues.
