Conditions

There are about 200 different musculoskeletal conditions. Arthritis is a term used by doctors to describe inflammation within a joint, while rheumatism is a more general term that's used to describe aches and pains in or around the joints. Because there are many possible causes of these pains doctors don't often use the term rheumatism and will usually refer to these problems either by a specific diagnosis or according to the part of the body affected. Doctors sometimes use the term 'musculoskeletal conditions' or 'the rheumatic diseases' to refer to a whole range of conditions that affect the joints.
