Everywhere I read that an EMG is one of the first tests they might do for MG, right? (And the AChR.) A doctor told me that "if someone has an abnormal EMG they definitely do NOT have MG, they have MD." That's false right? I just want to make sure I am not crazy

I am pretty sure he was just trying to mislead me on purpose because he decided that I was just a silly hypochondriac... sigh. But it's still weird for him to make untrue statements.
With MG, you could have any combination of these 3 tests being normal or abnormal right? I am just trying to start to decide which of them I should get done - maybe 2 of them or all 3. (Doc will order the ones I want.) But yikes about the money and getting poked and prodded so much at once. (Well actually I think my ins might cover these 100%.)
