Allan, I know EXACTLY where you are coming from. I ask myself what makes the difference all the time. I have been on monthly IVIG since Feb. 2010. I also take Imuran and Mestinon. I have been tested for carpel tunnel syndrome and it was negative. I try to explain to everyone what my hands feel like. It is like I have mittens on all the time. I can't really feel and grasp like I could before I got MG. I feel it has to be connected but my dr doesn't have any other thoughts.
I just have to enjoy the good days and just wait out the really bad periods. I hope that you have some better days coming, Allan.

Take care ~ Melanie
