Clinical Information

A disorder characterized by inflammation involving

the skeletal muscles.

An inflammatory process affecting the skeletal muscles.

Causes include infections, injuries, and autoimmune disorders.

Inflammation of a muscle or muscle tissue.

Inflammation of skeletal muscle, not including inflammation of

cardiac muscle

Inflammation of skeletal muscle.

Myositis is inflammation of your skeletal muscles, which

are also called the voluntary muscles. These are the muscles

you consciously control that help you move your body. An injury,

infection or autoimmune disease can cause myositis. The diseases

dermatomyositis and polymyositis both involve myositis.

Polymyositis causes muscle weakness, usually in the muscles closest

to the trunk of your body. Dermatomyositis causes muscle weakness,

plus a skin rash. Both diseases are usually treated with prednisone,

a steroid medicine, and sometimes other medicines.
