So sorry you have to go through this frustating crap, I know how you feel though, I got my MG diagnosed, now am going through loads of testing for my overlap. The testing never seems to end, & the worst is, they never tell you everything, they keep notes until it adds up to something, or they mention what they think it is, & take it back next visit ! Thats always a good one.
Take care,
Mary
