Need some enlightenment TSH @ 0.08 Free T3/T4 low - post ThyCA

[qcikid]

Had TT in August and RAI in September for follicular cancer.  Been on 150mg of generic synthroid since September.  Endo says my TSH level is good (0.08) but am still super tired and have a lower body tempature than I had before I lost my thyroid.  My Endo says the tiredness and cold extremities is not thyroid related and my levels are "fine"; come back and see me in six months.  My primary care doctor says the cold extremities, horse voice, lower body temperature and tiredness is related to my non-existent thyroid; he tested my adrenal gland (all was well) and had my TSH level with Free T3/T4 tested.  My TSH is "almost non-existent" at 0.08; my free T4 was 1.8 and free T3 was 2.9.  From what he said both are on the lower end but still in the normal range.  Is this normal or something abnormal?  Do I just need to be more patient? Why do doc's sometimes just follow the numbers and forget all their patients subjective sympthoms?

Will have to get a copy of my labs from my primary care doc - he called me this evening with the results and I didn't have a pen to right down the reference ranges he cited. Will update on Wednesday when I return home from a business trip. Thanks and I'll look up your recent post to Rohai

I am a bit confused that you said that your FT4 was in the lower end of the range.  Would you please confirm the reference ranges used by your lab for the FT3 and FT4?

Also, your symptoms and your test results likely fit a pattern that we hear about many times daily on the Forum.  To understand why I say this and what it means for you, please read my recent post to Rohai.
