Over a week ago I was off roading with my father in his old chevy truck. We got out of the truck and hiked up a hill, and then I started to notice a real slight pain in my right testicle. The pain hasn't gotten better or worse, but only hurts when something comes in to contact with it. Sitting, standing, laying in bed, no pain, but walking or touching or any contact hurts, but not the whole testicle, just part of it. I can touch the top and feel pain, touch the bottom and nothing. I haven't had any blood in my semen or in my urine, no swelling or discoloration, I haven't had any pain anywhere else and no fever. Is it possible I just bruised my testicle and should lay and rest for a few days, or is it more serious?
