I had a TT last year for a small, noninvasive follicular tumour. everything went well post op, but I just haven't felt quite right since. My surgeon said that most people felt well with a TSH of around 2, and that's what he aimed for. However, my surgeon discharged me to the care of an endocronologist when I was three months post op, and my endo says that's too low and wants me to be about 5, which I currently am, with a T4 of 11. I know this is something I need to sort out with my doctor, but I'd be really interested to know what TSH level other people on levo feel well at. I'm just so tired all the time and I feel my brain has a time lag on it.
