I hope someone can help with this. This morning my husband was taking off our 3 year old son's pull up (which he only wears at night) And we noticed that his penis / foreskin area is red and very swollen. My son also said that his pee pee hurts. My son has been sick, but hes not on any medication. He has a slight head cold. Does anyone have a clue what this could be? I've never experienced anything like this and I have an older son whos almost 6.
