I had Gleason 3+4 and RARP in 2019
I had various discomforts in pelvic area would come and go for many months maybe two years or more afterwards. Pain in anus, kicked in the balls feeling, "broken" feeling in penis, and general not right feeling in pelvic floor. I don't recall rib pain except around the stab wounds for a little while.
Pelvic floor discomfort would get worse if I lifted anything heavy or slipped or did some unusual movement
My surgeon put it down to adhesions and scarring and told me to keep walking as the best exercise, but that eventually I would have to start challenging the scar tissue. There's a lot of stuff been rearranged down there
And gradually over time it got better and better. I had a few abortive attempts to get on my bike, eventually I was able to persist and now up to 50km and I don't feel anything
Obviously this is just me - but my experience is it goes away. It was up and down sometimes 2 steps forward one step back. Keep going, it takes time.
