If Mestinon helps me with muscle strength and balance, is that enough to assume that I have MG even if all my tests come back normal? I am only on a low starter dose of 20mg tid(60mg daily) but it makes a noticeable difference within 20 min in my ability to walk and this morning it helped me with swallowing although I still couldn't eat oatmeal, but I was able to choke down a banana.
