I had a sore throat that set in around Day 2 and last until about Day 4 (if I remember correctly – you can search my posts for confirmation). I felt hyper for a few weeks and ended up having to go back on PTU as my thyroid dumped, and I never stopped taking my beta blocker (still haven’t 18 months after RAI), so that helped. I got a cold about a week after, but that was likely NOT from the RAI as much as it was the combination of working in healthcare, sitting in a hospital waiting room for 3 hours waiting for my RAI dose, and being on prednisone before RAI to reduce eye effects. It was six months before I was officially hypo but I felt good within a few weeks after RAI as my thyroid slowly died off.
Good luck, and know that this is the start of your recovery!
