I have been having infusions of Acterma and wondering when it will start working. I have poloymyalgia Rheumatica and the pain has taken me to the limit. I can't use my hands , headaches, hip, leg, thigh pain severe. I am hoping that after a couple more infusions, I will feel better. I have to keep asking my doctor for more prednisone . Doctor seems to think the Acterma will work and doesn't want me on prednisone. I am coming off of a 15 day coarse of the prednisone now and starting to feel the pain again. I have had 1 infusion and next one is this week.
