Polymyositis: Is this a flare up?
I am a 67 year old man who had a bad case of polymyositis 10 months ago. I responded well to prednisone (starting at 140 mg per day) and was down to 6.25 mg per day when I went on a strenuous hunting trip this fall. I came back early due to muscle discomfort particularly in the shoulders. After 2 weeks, my muscle enzyme tests came back normal, but now after another 3 weeks I still hurt, even more than ever. Is this a flare up and why did the tests come back negative?
