Kathie thank you. I live near Beckley WV. I tried to get info from WVU yesterday since they are a MDA clinic, it is 4 hours away, I'm going to call again Monday. I started taking Pred. a month and a half ago 50 mg a day. Yesterday I started on Imuran. I get a wierd feeling in the pit of my stomache when the mestinon starts to wear off, I guess it's just air hunger. I went to the local er 3wks ago because I felt so bad, they gave me a shot of steroids and then I got a shot every other day at my pcp's for a week, it helped a little until I could get ivig. Does mg affect your vision? Mine is like looking through the heat rising off a car in the summer, it's distorted, it's also double.
