Arthritis

Arthritis is an illness that can cause pain and swelling in joints. Over time, the joint can become severely damaged. Joints are places where two bones meet, such as elbow or knee. Some kinds of arthritis can cause problems in other organs, such as your eyes, or in your chest. It can affect your skin, too. These problems may be caused by inflammation (in-flah-MAY-shun), a swelling that can include pain or redness. They are telling you that something is wrong. There are several kinds of arthritis. The two most common ones are rheumatoid (ROO-mah-toyd) arthritis and osteoarthritis (AH-stee-oh-ar-THRY-tis).
