This is a tough call. I had RAI twice and had virtually no symptoms either time, but I’ve seen a number of postings from people who felt pretty lousy after RAI. Perhaps the doctor has a better idea of how often people have difficulty after RAI. Since you’ve already been on PTU for awhile, is he giving you a reason for the urgency? It sure sounds like you have enough on your plate as it is.
I hope things go better for you and Lou soon. You’ll be in my thoughts.
