I see from others that you are not alone, I too get this at times and my Dr. ran all kinds of tests and said the same thing.. must be MG related. The trouble with MG, in my opinion is that if the Dr. doesn't know what it is than it is said to be the MG. So I myself just say OK, and don't report things anymore, gets me to aggrivated to be tested and told "oh it must be the MG" almost like before we are DXed and told it is in our head. I hope it doesn't come back.
