Welcome, Billye! I only belong on this forum by virtue of once having had Graves' Disease. I'm currently underactive, on Synthroid for several years now. I can't say I'm freezing all of the time, the hot flashes take care of that!!!
But my normal temp is anywhere from 1 to 2 degrees below the average. I suppose that is from the thyroid. I remember when I had Graves' as a child, I sweated constantly. Now I try not to get too hot, despite my slightly lower normal body temp, since I have myasthenia gravis, which tends to get aggravated by heat. I usually post on the MG forum, but like to keep on eye on this one as well.
Which of your conditions causes you to be freezing all of the time?
Hugs,
