Well I went out to the lake for Memorial Day weekend on my pops boat and did a hand stand off the top and flipped to the water...when I hit the water it smacked the back of my testicles pretty hard and it is now bruised like down my raphe and my left testicle feels like it is either trying to pull itself up and a slight tingle happens every once and a while up at the higher part of my vas deferens...could anyone tell me if this sounds serious or will it heal?
