Good luck James! It is great you got an earlier appointment.
This doctor does not test for co-infections. I always suggest having them done. If you want to be tested for them, tell him you want to.
Write down a complete history of when you became sick, what your symptoms are etc. Write down questions and I suggest writing down his answers as best you can. It is hard to remember everything. He will give you a lot of print-outs with information.
Let us know how it goes, okay?
