Hi Carol:

Sounds like you have a great doctor. I'm the same way..... won't even get my blood work tested b/c it's meaningless to me with high levels of FT3 and FT4. Having been hyper, I know what it feels like and I'm nowhere near that state.

Like ysabella says, thyroid resistance can mean taking higher amounts of thyroid hormone to get into the cells. Many doctors don't treat that way and they leave you grossly undermedicated.

Good luck!
