arthritis

A disease characterized by joint inflammation. Joint injury can be caused by trauma or aging. The general term arthritis includes over 100 kinds of diseases, most of which last for life. In many forms of arthritis, injury is caused by the uncontrolled inflammation of autoimmune disease, in which the immune system attacks the body’s own tissues. Common kinds of arthritis include osteoarthritis and rheumatoid arthritis.
