Sorry you do not have the resources do this; stop worriying about nice protocols, and when you hear about an amazing doctor, go and see him; end of the story; I oculd have saved so much money and minsery had I heard about this doctor before.
But I must say that instead of trying to find a cure, you are worried about getting your "feelings" hurt; again if someone had scolded me when I was sick and told me get the hell to Cahill I would have been so grateful.....to that person; who cares about being nice.... so long as diagnosis is done and treated and gotten better.
