Are you at a university center now? If so, then maybe it's time to consider MAYO or something like that? I felt the same way a year ago.. I thought I was going to die while everyone was just slowly trying to figure it out.. i couldnt' breathe, talk, hardly walk, hold silverware, all while my heart rate and GI systems were going crazy too! Do you like the Dr's your seeing? Do you feel they really "get" you? If you can find someone you feel like you are really in good hands with that helps tremendously.. Have they done a muscle biopsy? If not, maybe they should? Steriods can actually make many neuromuscular disorders worse, as far as the weakness goes.. especially in high doses.. How are you feeling with your neuro symptoms?
