Yea, I have nodules on my thyroid and I have Hashimoto's thyroid disease. My nodules were first discovered when I was 20 years old.
You will hopefully either be scheduled for an ultra sound so the specialist can look closer-- or (and perhaps after the ultra sound) you may have a biopsy(sp?) done to rule out cancer........ not to worry you though-- many many nodules are just that-- nodules and not cancer-- but it's good to get it checked -- with that said, thyroid cancer is one of the most curable of any cancer.
I've had to have my levothyroxine upped many times over the years as my thyroid gradually shuts down.
Good luck with this!
