Why do my Testicles Hurt?

Testicle pain may be caused simply because someone gave you a good pop in them and bruised them lightly. However, if pain persists for more than a day, is excruciating, is accompanied by swelling, or is accompanied by blood in your urine or semen (you know how to get semen from yourself, so I wont explain that) then you should probably seek medical expertise very soon.
