On January 27, 2010 I received RAI. Two weeks after my proceedure my neck swelled up. After calling my different doctors I was finally seen by my Primary care. At that point I was placed on 60mg of steroids for a week. As soon as I stopped the steroids, my neck swelled up again along with the worse burning sensation. I ended up in the ER where they once again put me on 5mg of Steroids for 1 week. I was finally able to see my Endo yesterday. I was told that 1 in 300,000 people have this happen. Surprise!!!!!! I understand this does not happen to everyone but I do think they should have warned me about it. Everything I read prior to having RAI said nothing about this happening. I am lucky at this point, it has been almost a month and my levels are great. Just wish I didn't feel so miserable.
