I know it. It's frustrating and unfortunately riddled with compounding misdiagnoses. It is just the way it is here in the u.s. In france, I met a very gracious doctor who listened to reason and pescribed me what I needed without hesitation. He gathered all the circumstantial evidence and the decision was obvious. He made the right call. It italy the doctors wanted to be helpful but wanted tests run. Which is natural, of course when the tests come up negative then that is where the problem lies. In tijuana the doctors I met were some of the most gracious and helpful doctors I have come across. Wanting to help you any way they can. I guess here in the u.s. parasites are such an anomoly that doctors maybe don't believe people can have them. I don't know, I just know that very seldom do I get the treatment that I really want and need regardless of the situation I go in there for. It just leads to alot of self treatment.
