I am right in the middle of my radioactive iodide thyroid scan. I went in & took the two capsuls after no eating from midnight. I go back in a couple hours for the actual scan. The no eating was the worst part. I was totally shaky, headache, etc. The capsuls did make my thyroid feel more “swollen” or pressured. But my neck looks the same – not growing with the feeling of the swelling. Hopefully the rest of this will be painless. The tech assured me that there would be no reactions.
Good Luck.
