Rheumatoid arthritis (RA) is an active, inflammatory, peripheral, systemic, symmetrical arthritis afflicting three women for every man. Now let's break down this medical jargon. Active means that RA is an ongoing process lasting for years. In general parlance, inflammatory means fiery or provocative, but here it means swelling, redness, tenderness, and pain in your joints. Peripheral tells us that RA involves mainly the joints of the arms and legs, in particular the fingers and wrists. Systemic means that RA, unlike osteoarthritis, affects the heart, lungs, and eyes of some patients in addition to the musculoskeletal system. Symmetrical is the key in distinguishing it from other kinds of arthritis. RA usually involves the same joints on both sides of the body: the knees, the wrists, or the joints of the fingers, for example.

 RA is one of the most common forms of arthritis. It affects mainly women in their forties, but it can also occur in children and in seniors over sixty-five years of age. It is an equal opportunity condition, affecting rich and poor alike. Arthritis occurs more than half of the time in the fingers, wrists, shoulders, knees, and ankles. Besides pain in the joints, it also causes trouble in other parts of the body, although involvement of the upper spine or lower sacroiliac joints is unusual.
