Just had my annual exam, and my TSH came back .014 Normal range is .40-4.00 Yikes!! My doc wants me back in a month retest. I am reading and it shows that a low TSH would be hyperactive... which I do not feel at all! If anything I have gained weight. I do not have anxiety, I don't have trouble sleeping or any of the side affects of hyperactive thyroid. I'm kind of freaking and hoping this isn't thyroid cancer :(
