had this couple of years ago, think I may have posted on here about it, had ache like toothache going from testicle to my kidneys and back, left it and left, coz I'm a man and I can beat anything right... wrong, I ended up in tears in agony whilst on a trip to Scotland v Brazil (Emirates game) convinced I had testicular cancer and was dying, turned out to be an infection in my pipeworks needing antibiotics... Get checked mate!
