Can you try a completely different pdoc to see if another one will help you? Remember a while back I suggested you take advantage of being in a city with really great hospitals, like McClean, MassGen, etc? Now might be a good time to see if they can help you. You'll need to go to an ER because I'm sure they can't get you in very quickly otherwise. But just go to one of those great hospitals and explain how you are feeling and see if they can help.
