Well that will be next if the next ultrasound warrants it, I am so mixed on that too, cause I have a cousin who had thyroid cancer, they removed the thyroid and he is permanently on thyroid replacement meds.
Almost all the women in my mom's side of the family (and 1 out of every 4 women) have thyroid disorder(s) and are on Synthroid, I do not see them much so I do not know if any of them have nodules, too.
The endocrinologist told me, the ultrasound report suggested in the future the test where the radioactive dye is used to trace stuff. But my doc prefers to go right to needle aspiration,and have sample analyzed, then if suspicious go in and biopsy,surgery.
She assured me the nodules were so small that they really didn't warrant any quick action, but start seeing what upping dose of meds do.
Duh, is me. I am at the point I will look into going to a University hospital if I do not get any satisfaction in the next couple of months, I'm so tired of years of feeling unwell.

Thanks for the reply and info, I really appreciated it.
