I was diagnosed hypo thyroid with hashimoto's about 7 years ago and have done fine on synthroid 50 mg since that time. About August of this year I noticed the sudden growth of my thyroid, huge and noticeable goiter where only the month before I had nothing, so I made an emergency appointment to my doctor. She tested my tsh (only, no other thyroid tests) and got a reading of .02 and discontinued my synthroid. I went in for a repeat TSH four weeks later and it was still .02. I went four weeks later and it is .02. My doctors says she suspects Graves AND Hashimotos. How is this even possible? She called today and recommended repeat testing in 6 weeks.
I am uncomfortable with this plan. First off, the huge goiter appeared nearly overnight, and that doesn't sound good. Second, nothing is changing, so what exactly is she waiting to find out? She hasn't answered these questions, just ignores me. Can the goiter shrink? If not, what are my options to get rid of it? I don't like it or want to keep it. Is there a possibility it is more serious? Is doing the TSH only acceptable? I mean, if it not changing, it seems like maybe more information is something to think about, but she doesn't think I need anything by TSH test. Should I just keep on going for another 6 weeks (which is really more like 8 because of the holidays) and not treat this very low number?
