Rheumatoid Arthritis - Cause

The cause of rheumatoid arthritis (RA) is not fully understood. Genes play a role, but experts don't know exactly what that role is. For most people with RA, the disease doesn't run in their families and they don't pass it along to their children.

Other causes of joint pain include osteoarthritis, lupus, and gout.
