I just called my GP, and they are going to get back to me, for a couple of days I noticed some lumps ( not red or itchy) but they are sore to touch., now it is starting on the other arm., could this be from prednisone? I was thinking maybe fluid build up.,, but I will probably be seeing my GP today., I am also going to discuss with him about going off of this prednisone., till I see the other specialist (neuro who specializes in MG in August hopefully sooner., it seems the prednisone side effects are causing me more of a problem then my symptoms from MG.......Any one ever have these lumps? Could these be lymph nodes swelling? Waiting to here from my GP., will let you know what he says
