Arthritis

Arthritis (from Latin for "joint swelling") is a group of conditions that affect the health of the bone joints in the body. The two primary diseases causing arthritis are rheumatoid arthritis, an autoimmune disease, and the more common osteoarthritis[?].

Septic arthritis[?], caused by an infection of the joint, and gout are also common causes of arthritis.
