My endo never checked for the antibodies. She only checks TSH. My TSH has always been near 1. On my current blood draw, I had her check off almost everything on the thyroid panel (free T3, free T4, and antibodies) this time. Anyway, I figure something's going on because I've been losing hair, getting rashes, and my ca levels are elevated. The tingling in arms, which I've had for 10 years, seems to be about the same. BTW, does anyone experience tingling in their lower extremeties? I've had MRIs in my neck and spine years ago, and they were clean.
