There are very few allopathic who know how to diagnose and treat thyroid issues. Please read "Stop The Thyroid Madness" or Mark Starr's book (which I can't find). You need to get the right lab tests first and foremost. Then you have to find a good doctor, which often times will be and N.D. an O.D. or Chiropractor. Dr. David Borenstein also has a good website. You'll learn that many cannot convert T4 (Synthroid) to T3 and do better with Cytomel. I'm still dosing myself trying to find what's right for me. It's a minefield, but there are many in the same boat. Also go to Datis Karhazzian, N.D.'s forum to talk with people who have your same symptoms.
