Please go see an ENT to make sure everything else is okay...
You really do need the swallow test.
Have you been tested for Free T3 or was it Total T3. Could you please post the result and reference range, for whichever it was?
Lacking some vital information, but wanting to try and help you understand what is going on, let me give you a couple of scenarios that we hear quite frequently from members, and see how that fits your situation. The patient has had a TT or Hashi's and is suffering with typical hypo symptoms. If the TSH result is high enough, doctors with the "Immaculate TSH Belief" will prescribe a T4 thyroid med. Then, when the dosage gets high enough for the TSH to be suppressed to the lower end of the range or below, the doctor says that you have become hyper and must reduce meds. Meanwhile you still have hypo symptoms, not hyper, and need an increase not a decrease.
The next scenario is that the doctor relies mostly on TSH, but will also test for FT4 as well. As long as the TSH and FT4 are within the so-called "normal" ranges the doctor declares that you are doing fine and that those nagging hypo symptoms you still have must be due to something else. Do either of these sound familiar?
The scenario you really would like to have is that the doctor is a good thyroid doctor that treats a patient clinically by testing and adjusting FT3 and FT4 as necessary to relieve symptoms, without being constrained by resulting TSH levels. This type of thyroid doctor knows from experience that a suppressed TSH does not mean that you are hyper, unless you have hyper symptoms due to excessive FT3 and FT4 levels. If your FT3 and FT4 levels are within the almighty reference ranges, how can they be excessive? They're not, It's just that TSH is frequently suppressed when taking significant doses of thyroid meds. A good thyroid doctor also knows that the reference ranges are far too broad and that they should be used as guidelines within which to adjust FT3 and FT4 as necessary to relieve symptoms, since symptom relief should be all important, not test results.
You can read more about clinical treatment in this link, written by a good thyroid doctor for patients that he is consulting with from a distance. The letter is sent to the PCP of the patient to help guide treatment.

So in my opinion, the first thing you need to do is to get testing for FT3 along with FT4 and TSH. I expect that you will find that your FT3 is way out of balance with the FT4. By that I mean that your FT3 is lower in the range than your FT4, indicating lack of T4 to T3 conversion. This is a frequent occurrence when taking heavy doses of T4 meds. If that is the case, it indicates that you need to change your meds to include a source of T3, either by switching all, or part, of your meds to a T4/T3 combo type, or by adding a T3 med. The objective is to increase the level of FT3. FT3 is the most active thyroid hormone. It largely regulates metabolism and many other body function. Scientific studies have shown that FT3 correlated best with hypo symptoms, while FT4 and TSH correlated very poorly.
If your doctor resists testing for FT3, then insist on it and don't take no for an answer. Remember that you are the customer. While you're at it you should also find out if the doctor is going to be willing to treat you clinically, as described above. If not, then you will need to find a good thyroid doctor that will do so.
When test results are available, please get a copy and post results and reference ranges shown on the lab report and members will be glad to help interpret and advise further.
I posted but my post was so long it's easily forgotten. My TSH level was up from .528 in Dec. 2011 to now being 1.810 and my Free T4 was up from .924 to 1.05 . They did not check my Free T3 this time around. Thanks :)
As a starting point, please post your thyroid test results and reference ranges shown on the lab report so that members can assess the adequacy of testing and results.
