Thanks for your answers, all. I realize that I should consult, but I have a doc who is very, very difficult to talk to. He doesn't answer questions but tends to just pat me on the hand, say "there, there...".
I don't feel comfortable asking him anything anymore. Once he even came at me with: "why are you concerned about this (side effects of drugs he recommended).....do you have any medical training?"
I tried to answer: "well no, but I know my body well...." and he dismissed me, as if I were invisible. I would love a new doctor, but in Canada, with govt health care, it's almost impossible to switch once you have one.
