Its totally ironic that this post from you appeared here. Just a few short days ago an OB/GYN posted some "expert" activity on Bio-identical hormones and addressed the TSH to me privately along with other things. I requested he publically posted our correspondance together that we had privately and he did! - Here is that link:

take some time and read it - in its entirity... It is valuable to your health.
You actually "fit the bill" on exactly what I was advocating for in the messages we exchanged and the universal testing you are having right now are probably not doing you any service on getting to the root of your issues.
To look at thyroid only right now in your case..... the TSH lab you are having isn't doing you any justice in really seeing the "picture" of the disease at all. Lumping one "pitutiary response" test as the TSH is.. hardly tells anything.
I feel you may have a doctor just like this one that posted that article and may not be taking advatage of the other tests needed to get to the root of your issues and get you balanced back again.
Read the responses on the post above. I think we can walk through many things to help you on this community after your read it so you can get the quality care you need to find out what's going on.
