Just a bit of info, if you are going to have thyroid tests run, MAKE SURE they run the Free T3 and Free T4 and not the standard T3 and T4. There is a difference, if they don't check your Free levels its a waste of time.
I went 3 years with hardly any thyroid function even though I was begging for help but I kept testing "normal" because they were not running the most definitive test of the Free's.
