Yep - you are definately hyper. Bless your heart. You might want to go ahead and have the scan. Maybe you could ask K9 about the scan. I had a doctor once tell me it was the definitive test for Graves, but I was told later that was not the truth. I was also told by a doctor once that I may have never had Graves (even though that was my original diagnosis) but Hashimotos all along. I think he was wrong, but I was quiet distraught when he told me this b/c I had RAI! I really do think these may be transient numbers for you though since you were not hyper just a little while ago. I would say it's definately too early to go the RAI route. (I just kinda went along with it all... scan, sure... fna biopsy, sure... rai, sure... etc. -- <I also had nodules, btw>).
As you can see, I am confused about your situation even though i was in a similar situation. I really don't believe doctors know as much about antibodies as they would like for us to believe because I swear I ask every doctor I see to make it clear for me and it's still clear as mud
