Rheumatoid arthritis (RA) is a form of arthritis that causes painful swelling in the lining of joints. This swelling can eventually cause bones to wear away and joints to become deformed. Rheumatoid arthritis is different than osteoarthritis which is often caused by wear and tear, sports injuries or the normal aging process. Although all forms of arthritis can cause join swelling and pain, rheumatoid arthritis is an autoimmune form of arthritis which means that the body's immune system mistakenly attacks the lining of the joints. In addition, the disease can also cause other problems in the body including fevers and fatigue. Although rheumatoid arthritis can occur at any age, it most commonly occurs in individuals between the ages of 40 and 701.
