Re: went back to the endo..
HypoT - in general - is associated with high TSH and low FT4 and/or FT3.
Your TSH wouldn't be considered high unless either or both of your FTs are low. Going by common ranges for FT4, yours wouldn't be particularly low; in fact, it would be very good in a common range of .8-1.8. So on paper, you'd be considered by most MDs to be euthyroid... neither hyper nor hypo.
But it isn't that simple for most people. To really get an entire picture of where you are, you ought to have FT3 measured as well. If it's low, that could be the reason why you have continuing symptoms.
