Any unusual symptom should always be mentioned to you medical team. I am guessing your husband groin discomfort is caused by the treatment. From what I remember 13 years out, I obsessed with every creak and pain from back etc that I was worried about something else might be wrong. That lasted 4-6 months when I learned to drop the thoughts. Again, still let your URO know about everything.
