Arthritis is inflammation of the joints (the points where bones meet) in one or more areas of the body. There are more than 100 different types of arthritis, all of which have different causes and treatment methods. The symptoms of arthritis usually appear gradually but they may also occur suddenly.ome forms of arthritis are caused by a reduction in the normal amount of this cartilage tissue. Osteoarthritis, one of the most common forms of arthritis, is caused by normal wear and tear throughout life; this natural breakdown of cartilage tissue can be exacerbated by an infection or injury to the joints.
