graves/hashimoto? confused

[alikat1205]

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?

I know TPOab was elevated.  I don't know about the other.  As for my most current testing, I didn't get numbers.  All the doctor said was that my TSH went from 0 to 3.6 which he liked, and my free TSH was normal.  I don't know anything else.

Remission of Graves' is possible.  Many people go into at least temporary remission.  

I know your TSI was elevated, and I just looked above but couldn't see if your TPOab and/or TGab were also???

If you have both Graves and Hashimotos, your thyroid can fluctuate a lot. You should probably get tested more than once a year. Also, is your TSI in the normal range? Wasn't your last TSI test out of range?

I have been completely off all medication for almost two years.  Other than not liking my current weight and terrible acid reflux, I feel fine.  I just don't like the goiter in my neck, obviously.  Remission is possible?  My doctor says just re-check in a year.  WOW

Are you taking thyroid meds now?

It's possible that you are in remission.  

How are you feeling?

ok, I just had my levels tested again because I refused RAI, and my dr. says I am in normal range!!!! (still have goiter).  TSH 3.6 and free tsh normal (don't know numbers).  Is this possible?  now what?
