I just had shots and scans. For me hours after shot I'd feel very slowed down, nauseous, body aches but by night was gone. Only issue I had with scan was I don't do well in tight places and didn't like the arm wrap but the 2nd scan I took something to relax me and it was over before I knew it. I'm waiting for info about the i-131 therapy now. Good luck..Kim
I just recently had Thyrogen injections and I did not feel any side effects from them at all. I can't speak for everyone here, but I think Thyrogen is a wonderful alternative to having to be hypothyroid. Just make sure your insurance covers them as they are expensive.
