In the interim, I am very confused, and frightened about these weird diagnoses and treatment recommendations. Any insight would be greatly appreciated. I am currently being sent on to yet a 3rd doctor, a so-called "Lyme" specialist....
Another important consideration is the levels of the actual, biologically active thyroid hormones, which are free T3 and free T4. FT3 and FT4 are the portions of total T3 and total T4 that are not bound up with protein, which renders them inactive. FT3 is actually the most important because it is four times as potent as FT4, and FT3 correlates best with hypo symptoms. Tests for total T3 and total T4 are somewhat obsolete and not very helpful.
You didn't mention TSH, which is every doctor's favorite test to run. Unfortunately it is not adequate as a diagnostic to determine treatment. It is only useful as an indicator to be considered along with the other, more important ones. So my suggestion is that is you haven't had FT3 and FT4 tests done, then go back and insist that be done and then post the results and reference ranges used by your lab and members can help interpret.
