What Is Myositis?
6. Necrotizing Myopathy
Individuals who develop this form of myositis previously were given a polymyositis diagnosis due to the lack of a rash associated with other categories. However, individuals with this form experience high rates of muscle cell death and low rates of inflammation.
As with polymyositis, people with NM tend to experience weakness in the muscles closest to the center of the body. Other symptoms include difficulty standing up or climbing stairs and difficulty lifting the arms over the head. Falling is a frequent occurrence as well. A person with necrotizing myopathy is typically chronically tired.
