I did have an RAI scan. My uptake was 83% and it showed a diffused pattern. My family has a strong history of diabetes, rhumatoid arthritis, some Thyroid trouble and Lupus. So even though I did not have antibodies, my endo said she was 99% sure that it was Graves. I still have a hard time believing that I have it. I did have the RAI and am not on thyroid replacement drugs. But I sure wish I would have waited on RAI–just to see what would have happened. I have a nagging doubt in the back of my mind that maybe I did RAI when I didn’t need to. Anyways–too late now. I wish I could allieviate my doubts somehow.
