Hi:
I had a toxic nodule about a year ago and had RAI. I had been taking Armour thyroid for the last 11 months with good results. Then, about 1.5 months ago, I felt my hyperthyroid symptoms had come back....hot, waking up early, less patience, etc. I stopped the thyroid medication last week and got new blood tests (at that point I had been off the medication for 3 or 4 days). My TSH is .8 now. Does that mean that the RAI did not entirely kill off my thyroid? Do you think that it's functioning has come back and the medicine was too much on top of that, or is it possible that the toxic nodule could be growing again? Also, I really don't want to have radiation again. Is it possible that the anti-thyroid medication can work for me?
