I have no knowledge in the areas you are seeking, but I understand your frustration at your doc. I am surprised that they even ran vitamin levels. MD's are not typically taught nutrition in med school, or at least not until recently. A Nutritionist might be your best bet. You might be able to get a list of such specialists in a book on the subject in your local health food store. This is what I had to do when systemic candida albicans was still a mystery to MD's. I was self-diagnosed, laughed at and sent to psychiatrists. But I saw 2 of the nutritionists and they both said essentially the same thing, which was, "there is no way you could not have this." Then they told me what to do about it. Although I am essentially ignorant of your situation, I hope this helps just a little, and I am sorry that you are another victim of the medical system. It might help to know that docs cannot help it [well, I suppose they could try]. They are educated in surgery and in drugs, drugs, drugs. lol. billie
