Teresamang,
When I saw your first post, I was thinking similar to pmcgall, that your treatment was good because of the lower-normal TSH of .74.
When I look at your Free T-4 and T-3 however, it seems to tell a little different story. Your Ft-4 is at lowest-normal (not terribly uncommon when taking T-4/T-3 combo). Your Ft-3 is just barely above mid-range (mid being 140).
While in some patients, this level resolves their symptoms, others nead a slight tweaking of their dose because their TSH over reacts and suppresses slightly more than it should with the dose they are taking.
Your Ft-3 could go up another 40 or 50 points and you would still be within normal range. This would raise your Ft-4 closer to mid-range.
Some Dr.s will not touch a dose level when seeing a suppressed TSH, despite the fact that TSH is not a thyroid hormone but usually an accurate reflection of the thyroid hormone levels. It is not accurate in all patients however and some need TSH suppressed to very low normal or even below normal. Dr.s will argue this point but is evident in these patient's blood test results.
In my case, my TSH has to be very suppressed to near undetectable(0.01), for my Free T-3 to be between mid range and highest normal. If my dose only places my TSH at lowest-normal (o.3 or 0.5), my Free T-3 will only be at mid range or below mid range and I will develop worsening fatigue and joint aches at that level.
Doctors fear inducing dose-toxicity if they suppress TSH but the fact is, some patients need a more suppressed TSH than others do. I'm not the only one who experiences this scenario but have seen this attested to by other patients over the years.
In my opinion, doctors should be willing to do a trial of a slightly higher dose in these cases because close monitoring with blood restests and patient symptom monitoring (for hyper type symptoms, e.i. increased heart rate, elevated BP etc...) will prevent any possibility of thyrotoxicity/over-treatment.
I admit these trials of dose tweaking require special attention but it is worth it, to keep these patients from experiencing loss of quality-of-life due to ongoing hypothyroid symptoms.
If dose tweaking doesn't resolve the stubborn symptoms, other causes could then be searched for.
This is non-pro, layperson opinion but even my own personal experience tells me this does happen, although it is not common.
