I have pain in the lowest part of my back (where the vertebrae connect to the pelvis) and every time it starts to hurt, my left testicle hurts, too. It's also the same if my left nut gets hit, it makes my lower back start hurting. I have a somewhat bad back, so should this be normal for someone with lower back pain?
I don't know the anatomy or physiology behind this, but I do know from experience that there is a connection between the nuts and somewhere on the lower back. I used to get pains in the ol testes a lot and from time to time the pain would shoot to my lower back.
Hopefully someone more knowledgeable can give more specific information on this.
