Still, I know some groups are funny about letting you see someone else in the same group.

Honey, if you're the one paying for it, YOU are the one who gets to decide which doctor you want to see. If they have a problem with it, just tell them that you will take your healthcare business (and dollars) to someone who wants your money.....

I hope you get some answers soon - and I am one of those people who tested negative on everything (one "iffy" result, but not by much). A Mestinon trial is what clinched my diagnosis - it took 90mg to start seeing a difference. If you DON'T have MG, you won't be able to take ANY Mestinon without feeling sick!
