My 9-year-old son just took a bath, and came out screaming that his penis hurts. It came on suddenly, and he says it is not swollen or red. He says the shaft burns, and when he peed, that burned as well. I asked him if he rubbed soap there (he washed with the usual soap), asked him if he had been doing what boys do (no), called his dad for advice, and now he won't come out of the bathroom. He is crying and says it hurts horribly.
