Polymyositis & Dermatomyositis Support Group
Polymyositis (PM) is a type of chronic inflammation of the muscles (inflammatory myopathy) related to dermatomyositis and inclusion body myositis. The inflammation is predominantly of the endomysium in polymyositis, whereas dermatomyositis is characterized by primarily perimysial inflammation.
The pain is like when you wake up and are stiff and you stretch after a couple of hours the pain subsides. This pain does not go away. I am currently not on meds for DM as I am in remission so that can not be the culprit. My fingers are beginning to look like hot dogs.
Many autoimmune diseases overlap. My doc is testing me for Lupus again which may be a problem. Once I was diagnosed with DM that is what we have been watching.
