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.
thats great your tests are normal though :)
My rheumy advised me to get a muscle biopsy in order to get a we-have-no-doubt diagnosis. Glad I did...my muscles were loaded with PM.
Purr,

The rheum I just went to said that it can take years and years to show up in blood work. It's really kind of disheartening to feel so bad and have the blood work say you are fine. You start to worry that everyone thinks you are crazy.
I also agree that it does take time for stuff to show up with DM/PM. My Scleroderma autoantibody did not show up until my third year with DM.
I hope you will be feeling better.
