Improper management of my thyroid? Why is my t3 not improving?

[irisgurl]

I started with a tsh of 5.96(h) and a normal t4. My free t3 was 1.89(l). I took synthroid 40mcg a day and cytomel 5mcg. Things became normal with my tsh after 3 months and my free t3 was getting better. 4 more months went buy and i am the worst I have ever felt in my life. I am so miserable. My tsh is now .12(l) but my t3 also began decreasing. It was last checked at 2.09(l) and falling. The majority of my symptoms are that of hypo even though my tsh is hyper. I think it is quite obvious that I am being over treated looking at my TSH but what about my free t3 then? How come it is getting even lower? It makes me think that my t4 isn't converting to t3? Please help.

Even though your TSH is suppressed below range, that does not mean you are hyperthyroid unless you have hyper symptoms due to excessive levels of Free T4 and Free T3, which it sounds like you don't have.  For confirmation of that, there are scientific studies that show that TSH is frequently suppressed when taking thyroid med.  You can read about that in Recommendation no. 10 on page 13 of the following link.  I also suggest reading at least the first two pages, and more if you want to get into the discussion and scientific evidence of all that is suggested in the paper.

Before further discussion, please post your actual thyroid test results and reference ranges shown on the lab report.  Also, please tell us bout the symptoms you have currently.
