Polymyositis

Polymyositis is an inflammatory muscle disorder that leads to a progressive weakening of the muscles. It is caused by an autoimmune response, in which the body's immune system mistakenly attacks healthy tissue. Symptoms commonly include muscle weakness and pain, as well as fatigue and difficulty with activities of daily living. Polymyositis is usually treated with a combination of medications, physical therapy, and lifestyle changes. Early diagnosis and treatment are important for maintaining muscle strength and quality of life.
