You go in and they inject the stuff into your arm. Then you wait a bit. Then you go in to have the scan. Can't really remember exactly what it was like, I know you have to lie very still for a while, and it feels a bit claustrophobic as the scanner thing is right over your neck and head. No pain involved, I remember the worst part being that I really wanted to move - having Graves does not go with lying still!!! They tell you nothing, you just go home and carry on as normal, results get sent straight to Endo. I was never on block and replace, just took carbi on it's own. I don't really know the pros and cons of one versus the other.
