Had crisis first week in July. Was on vent for three days and had 3 days of plasmapheresis. Did pretty well on mestinon, prednisone and cellcept. Although, not sure cellcept has taken affect yet. (other than the initial side effects which got better when my neuro suggested taking it with food). Anyway,feeling that squeeze around my ribs again and getting pretty weak again. Face, eyes, hands legs etc.Going for PE tomorrow. My question, since I was unconcious for the other PEs, is how long before I see a difference?
