But I am not interested in debating the "meaningless" distinction between functional medicine and traditional medicine with you. That debate is meaningless to me for the reason I am in this forum.

In the United States, it is my opinion, that if you want to go back to the beginning and look at it all over again because what you have done isn't working anymore, and the experts in your life do not have the answers, then your best bet is to pay out of pocket and to go to an evidence based trained physician who practices with a functional medicine approach.
