Wow - sounds like it turned out to be a lot worse than originally thought. You are exactly right, tho - listen to your body & when you just KNOW smthg’s not right, keep seeing Dr’s till one finds the root prblm. Good luck to you, hope you continue to be on the mend...
Wow - that’s a tough one. I think it’s possible this is due to bladder spasms, but have you spoken to the surgeon, and/or a Urologist? I’m guessing this may not be unique, it may be a bit unusual but maybe not unheard-of. The fact that the pain is abdominal makes me think it’s not just the prostate itself causing it. The problem is, so many of the nerves in that whole area - prostate, bladder, scrotum, penis, etc. - are interconnected & pain can radiate to other areas, making it difficult to determine exactly where its origin is.
I would definitely talk to your surgeon & then maybe a Urologist. They may be able to perform some type of in-office scan or test to determine what’s causing this.
Best of luck to you - sure hope you can overcome this very painful sounding issue. Check back in later & let us know what’s found & if you’re able to get some relief...
