How long have you been seeing him? That would make a difference to me.

I would also wonder if the treatment that he thinks will help will actually be helpful regardless of diagnosis. And, is it possible that I do have X along with some other things so we'll address X and then see what else needs addressing.

Sometimes Ts have to come up with a diagnosis quickly. For my insurance, they have to put down a diagnosis or insurance won't pay. Clearly T doesn't know what the real problem is after 1 visit, but they have to put something down. Is it possible that something like that is going on?
