You should never ignore testicular pain, as it often indicates a condition that could get worse -- much worse -- if ignored for too long. Anything from a hernia to cancer can cause testicular pain. The spermatic cord could be twisted, causing testicular torsion, which causes excruciating, fall-to-your-knees pain. Ignore it at your testicles' own blood-starved peril.
If you've taken a direct hit to the jewels lately, the pain may go away in the following days, or be a sign of a hematocele, in which blood pools between the protective sacs of your scrotum. Inflammation of the epididymis, a coiled tube located in the back of each testicle that serves as a storage and delivery system for sperm, can also cause testicular pain. If the discomfort in your testicle accompanies a tactile sensation that your scrotum is full of noodles, you've likely got varicose veins, known as varicoceles.
There's little in the way of good news if you suddenly feel testicular pain, and ignoring it in hopes it will go away may cause you to lose a testicle. The thought of it is enough to give you a headache, which we'll discuss next.
