Hi, All! I will try to continue. Sorry about the first post. Blood work came back positive for Mg. Nuro. started me on 60mg.x4 mestinon, got so weak I could hardly get out of bed, had trouble breathing, feeling like a large weight on my chest all the time.I Also had a feeling of chocking all the time. Nuro said I was entering crisis, had 5 days of ivig at home. Did not get the expected results with ivig, still very weak and vision has not improved. I started on prednisone, going up to 80mg a day,also nuro mentioned plasma exchange if I continue to have breathing or chocking problems. Is there any light at the end of the tunnel?
