When I went hypo, my shoulders and arms tingled like they were going to cramp, my heart rate slowed, and I was freezing. Then, a lot of my muscles (legs, arms, shoulders, butt, you name it) started cramping the next week. When I had blood drawn, the endo said my TSH was still less than .1 because it hadn’t had time to “bouce back” yet, and the other numbers were dropping from my severly hyper stage to “normal ranges”. He immediately started me on thyroid replacement.
I went hypo hard and fast and if you can nip it in the bud, I’d highly recommend it. (I didn’t plan around Thanksgiving:-)
Good luck,
Melinda
