Are you on thyroid medication? I have Hashimotos as well, and have wondered if my 1/4 of my thyroid gland that is left was somehow triggered to make too much hormone, and this is being caused by too much thyroid hormone (but not Grave's disease. I am currently trying to see if taking enough hormone to suppress my own thyroid so that TSH is super-low will work, fingers crossed. But I have received literally 0 feedback or help from doctors.
