I received a four-day round of infusions that ended four days ago. I felt progressively weaker after each infusion session with difficulty even walking back to our car in the parking garage. However I don't know if it was due only to the IVIg or to the meds which I have recently started (Mestinon and Prednison). I am new to this, diagnosed with MG just two weeks ago. It's a confusing, miserable, scary time and it feels like I've taken three steps forward and six steps back. I wish I could write something encouraging but this is not yet my time for that. Mark.
