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.

Giant cell arteritis (GCA) is a type of vasculitis – an inflammatory condition that affects the blood vessels.
Gout is often said to be the most painful form of arthritis. Symptoms include intensely painful, red, hot and swollen joints, and it most often affects the big toe.
Granulomatosis with polyangiitis is quite rare, which usually develops with ear, nose and throat problems. The general vasculitis usually involves the skin, lungs, eyes and kidneys.
