It turns out that I did have all the tests for the thyroid--Free T3, Free T4 and thyroid antibodies and they came back normal. I will post the results later--I am too tired and my foot hurts too much to get up right now and find the paper work. I asked my doc to prescribe armour thyroid anyhow--just to see if I might get some relief from some of the symptoms I have (that may or may not be from hypothyroidism). She agreed to give a try. She gave me 1/2 grain per day. Boy is this stuff cheap! My tiredness--extreme-- I have blamed on CFIDS. But it is not impossible that some of it might be thyroid issues. My intolerance to cold or even cool is getting to be a big problem. Anyhow, I am not sure what to expect from this trial with Armour. I am too tired to research it tonight--=maybe tomorrow.
