My 7 year old son just informed me late this evening that it hurts when he pee while we were at a restaurant. I noticed when leaving that he was walking gap legged, but yet still able to climb over rails jumping up and down. After taking a look, I noticed that his testicles are swollen. There was no blood in his urine and his penis seems normal. Is there anything I can do for him tonight until morning when the doctors office is open ?
