Weird pain in testicles. Or arched feet?

Recently I had pain in my testicles and back so got sonography done and was diagnosed with 29cc enlargement of prostate and cystitis. My doctor told me to rest and drink plenty of fluids and not to strain. I also have high 230 tryglycrides and vit de and b12 deficiency which I am taking supplements for. I again feel this weird pressure in my bladder area and random pain in the chords attached to my testies coupled with erection issues..this is what happened last time as well but when I rested and did nothing for a couple of weeks it got better...I have noticed when I ride my motorcycle for long periods something like this happens...is there any connection...i also have difficulty emptying the bladder . Urine culture and blood tests came out clean twice. Streching sometimes helps but why the random pain and pressure in bladder area and testis. Anything related to posture or arched feet?
