My 2 3/4 year old toddler has been saying for several days, maybe a week? (I've been sick and exhausted with the flu, so I didn't pay attention to exactly when it started hurting) that his penis ("pee pee place") is sore. He doesn't say it is sore all the time. Sometimes I ask him and he says it's okay. When I look at it, it doesn't seem red or irritated though. Several times when he said it was sore, I put some ointment on, but that doesn't seem to be making a difference. He usually wears underwear during the day and disposable diapers at night. Any advice? Should I take him to the doctor already?
