Not everybody gets a horror story to tell. My SEs for IGRT were the rectal ones you mentioned and during the last fatigue. Both cleared up very quickly after treatment stopped.
Your experience sounds a lot like mine. A year later and my PSA is down and looking stable.
I think you're doing fine.
All the best,
I'll be in the shop.
