What Is Myopathy?
5. Myositis
Myositis categorizes the onset of inflammation of the muscles used to move the body. An underlying autoimmune disease, an infection or an injury can bring on this condition. Age may also play a factor in its development.
Myositis is further diagnosed as polymyositis, dermatomyositis or sporadic inclusion body myositis. Polymyositis usually manifests as a generalized weakness in those muscles closest to the torso. Dermatomyositis may often exhibit a localized rash in the area of the muscle cramping or weakness. Sporadic inclusion body presents in those over 50 and includes a decreased ability to walk.
