Hiya Boschman,
I'm over two and a half years post RP now but I can remember a strong feeling of something heavy in the penis base and scrotum along with slight sorenes after my operation.This however, resolved itself after a couple of months. Since then I have had a few episodes of epididymis which seem to alternate between the testicles, but always clear up after a few days. One bloke told me he caused problems by trying to continue Kegel exercices with catheter in situ. I'm sure you will be alright.
All the best,Paul.
