Autoimmune myositis causes inflammation and weakness in the muscles (polymyositis) or in the skin and muscles (dermatomyositis).
What autoimmune disease affects the muscles?
Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body’s own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.
