Oh, while I'm thinking of these things. One thing you could try is asking for a letter or something. I tend to get them now and again, if my doctor's have told me something complicated. Mainly because they know I'l only whinge at them later if they forget stuff they've told me. I usually get a copy of the letter that they send too my GP and every other doctor I'm under.
I'm not sure if they have too do this, it's just I asked my docs one time, after I was going home confused and then getting wound up. It would always be worth asking, and it's something you can ask for politley and don't have to demand either.
Good luck in finding a new doc. Not every doc suits every patients needs, so if that's the case, it is best you move onto another doc, as they might just be the one who can understand what you need, and how detailed to go into things.
