What Is Myositis?
5. Polymyositis
Polymyositis is a progressive weakening of the muscles closest to the body core. Occasionally, the muscles in other areas are also impacted. More females than males develop the condition. Age of onset is typically 20 years old and up. Symptoms can appear over the course of days or months and there is no rash present with this type.
PM is characterized primarily by core muscle weakness. The neck, back, shoulder, hips and thigh muscles are commonly affected. Two significant indicators for the disorder are difficulty standing up from a seated position or getting up from after a fall. Some people experience swallowing difficulties or a chronic dry cough.
