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.

Arthritis can occur as a result of acute (short term) or chronic (ongoing) inflammation in a joint and its surrounding soft tissues.It can also occur after trauma to the joint (such as a broken finger) or possibly from genetic (heredity) and environmental causes.ymptoms of arthritis from any cause can include: 1  Pain limited to the joint itself. 2  This is the main symptom. 3  Initially, pain will come and go and made worse when in use (such as when gripping heavy objects). 4  However, pain is relieved with rest.
