Hi all, I hope some of you out there can help. Over past few months I have been doing everything I can to up my Vit D, B12, Folate and Ferritin all were on the low side after my last BH blood test. Im not on any thyroid medication as my doc says Im normal! My tsh was 4.1 my total t4 117. (68-145) my ft4 16.8 (12-22) ft3 4.1 (3.5-6.8) so Im confused my frees are low but my total t4 seems pretty good? Im considering self medicating but I have been putting it off as to be honest Im scared of making the wrong decission. Should I consider NDT or because my total t4 is quite high should I be thinking t3? Any advice appreciated as no matter how much I read I cannot decide what to do. I have a long list of thyroid symptoms and have been ill for 4 years so I think its time I did something about it.
