Arthritis (Juvenile Idiopathic)
Background
Arthritis means inflammation of the joint, which usually results in pain, stiffness and swelling. There are many causes of joint pain in children. However, most of these are not arthritis. There are many different forms of arthritis affecting children, some of which have specific names (listed in 'types of arthritis'.) Occasionally, it is not possible to give a particular name to a form of arthritis in a child.
