I have noticed that the tube running from my testicles and going into my groin is infllammed on my left side. I am aware that their are arteries and veins running allow with the ductus deferens as it travels through this canal, but I am not for sure what the problem is. I am experienceing a dull pain to the touch and a more throbbing pain the day after having sex. It really doesn't bother me during the day otherwise and I can run with no pain. Is this something I should go in for, or am I just overreacting?
