Arthritis is a form of joint disorder that involves inflammation of one or more joints. There are over 100 different forms of arthritis. The most common form of arthritis is: osteoarthritis (degenerative joint disease), is a result of trauma to the joint, infection of the joint, or age. Other arthritis forms are rheumatoid arthritis, psoriatic arthritis, and related autoimmune diseases. Septic arthritis is caused by joint infection. Osteoarthritis causes cartilage, the hard, slippery tissue that covers the ends of bones where they form a joint, to break down. Rheumatoid arthritis is an autoimmune disorder that first targets the lining of joints (synovium). Uric acid crystals, infections or underlying disease, such as psoriasis or lupus, can cause other types of arthritis. Symptoms of osteoarthritis may include joint pain and progressive stiffness that develops gradually. Symptoms of rheumatoid arthritis may include painful swelling, inflammation, and stiffness in the fingers, arms, legs, and wrists occurring in the same joints on both sides of the body, especially upon awakening.
