I have just been diagnosed as polymyotisis. But to make sure the neurologist wants to do a muscle biopsy. Has anyone gone this route before. I would like him to just give the prendisone and see if this works first. I really am scared to go for a muscle biopsy. My proximal muscle are painful and weak. My left arm has increasing become worse over the last 4.5 months that I have had this. I have been to 6 doctors, 2 bloods, 1 xray, and 4 months later I am still not on any medication and have to battle every day. Sitting up from a chair, bending down, can squat to take photographs, can not play golf, cant carry large items, unfasten my bra is so difficult as I can put my hands behind my back. I would love to chat with other "sufferers" of polymyotisis.
