The new guy probably already knows you saw the old one. You don't have to say anything more than you saw him, he didn't see himself as an MG expert and so you are seeing this guy. Why even bring it up if you don't have to? Short and simple and honest. Don't make it about the old neuro, make the appointment about YOU, as it should be.

If it were me, I'd let the new neuro just do his thing. Like Mary said, use "fresh" eyes on the situation.

Size-ism, eh? Probably that and sexism. I had a Hun of a nurse insinuate that my MIP was -24 to -21 (consistently) because I wasn't trying hard enough. Probably a combo of the fact that I'm blonde and overweight. And the fact that she is passive-aggressive and arrogant. People have a lot of prejudices they're carrying around, which are a lot weightier than you will ever be.

I really hope it goes well for you. Just go in there and stand up for yourself. You have a right to get really good care.
