Will respond back tomorrow, hang in there. Did the I.V.I.g. help you. Can you stay on it? Have you had a good G.I. work up. These meds can do a number on your tummy. Did the doc give you one of the stomach meds to ward off problems from the steroids? Steroids can make you weaker in the beginning.If you dont feel well like you wrote in your post call back the doctor, pronto. About the breathing, tell the neuro and I hope you saw a pulmonary doc, if not go see one. I hope you are ok, keep us posted. Hang in there. Try to stay calm I know easier said then done but it will make your M.G. worse also. Let your doc know too how you are.
