I am with you all the way, that's the message I received too a couple of weeks ago. It came from a neurologist, who'd tested for only one of the antbodies and who knew nothing of the term 'seronegative'.

My next stop is a rheumatologist, who hopefully knows more about MG than the student neuro did.

And may I say, good for you for saying that you're frustrated. It's good to let that stuff out!
