hi. i had a total thyroidectomy two moths ago. my feet and legs had been swollen and i had gained 20 lbs before the surgery. i lost 16 lbs and the water retention is not as bad as it was before the surgery, however, the inside of my fingers are very numb, i am not sleeping well, and i am still constipated,( all these symptoms i had before the surgery. i am on 224 mcg of synthroid since after the surgery. doc says my counts are norman, although b-12 is very low, 2.01. if my thyroid tests are normal why do i feel miserable? by the way i had been on synthroid for 20 years before the surgery
