You may expect to experience a soreness in your throat area. The thyroid “resides” in the throat, and as the RAI works to destroy thyroid cells, it causes some inflammation and soreness.
About one week — give or take some days — after the RAI, you can expect to feel more hyper than normal. Thyroid cells not only make thyroid hormone, but they store it for future use. So when the cells start to die off, they released their stored supplies into the body. This period of increased hyperness usually lasts but a few days.
Congradulations on being on the road to recovery from you Graves. I hope you are feeling much better soon.
