Oh my, I have thyroid problems in my family. My mom is on thyroid medications, and my sister had to have part of her's removed a few years ago. Have you had a biopsy done? Or are they going to look inside? Definitly, lumps on the throat need attention. I hope it goes well for you. Oh..even though my sister had part of her's removed she is not on meds and lives normally. I hope that whatever it is, you can deal with and move on with your life.
