Hi Barb,

I hope your endocrinologist or the nuclear medicine department explained the post-RAI feelings a bit. I definitely felt a little hyper since I had been off the PTU for a while. My doctor warned me if my resting heart rate ever got above 120, to go to the ED. I was still on beta blockers so it never got above 120, but it definitely hovered pretty close a few days after RAI and stayed there for about a week. I took it easy just to let my body get rid of all that thyroid hormone as well as the RAI. I had a bit of a cold/strep feeling for the first few days after RAI and lucky me, got the flu a few weeks later, but I think feeling lousy is something they don't warn you about. Inside, your body is going through all sorts of changes, some immediate, some gradual, and that's bound to affect each one of us in different ways. I felt like crap for almost a week, and then each day got a little easier and brought me one step closer to where I am today - in good endocrine health. Wishing you patience but also hope for a speedy recovery!
