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.
I will note here that too much salt intake really can contribute to this problem also, especially if you are on prednisone. The prednisone influences the way your body handles salt.
Keep us posted - Thanks
