Arthritis

Arthritis means pain in a joint (like your knee, hip, elbow or fingers). It is a common problem and generally affects older people, although there are some rare conditions that cause arthritis in children and teenagers. There are lots of types of arthritis. Some give you short-term aches in the joints and then resolve completely, others can cause long-term problems and permanently affect how your joints move.

The causes of arthritis depend on the form of arthritis. Causes include injury, metabolic abnormalities, hereditary factors, the direct and indirect effect of infections and a misdirected immune system with autoimmunity. Arthritis is classified as one of the rheumatic diseases.
