Would somebody tell me how to ask a question on this site? Here is my question: can my thyroid go overactive again once I have taken the radioactive isotope? I took the isotope in 1993 or 1994 and have been on thyroid replacement hormone successfully since then. But now I require ever-decreasing amount of hormone, and my doctor noticed an increase in the size of my thyroid. (I went from 90mg of Armour Thyroid to 100 mcg Levothyroixine and my TSH is at 0.089. All my doctor wants me to do is be rechecked in six months. Should I see a specialist before then?) I am worried. Thanks for your advice.
