Extremely tmi. But my son is 5&1/2. For the past like year ish maybe less he's had problems with his boy parts. It gets super swollen and red and if he pulls it back (he's circumcised) it sometimes has like white discharge. I'm very good at keeping it clean it is not because it's dirty...but he complains of it hurting. I took him to the dr a few months ago and they told me nothing is wrong. They took a urine sample for a uti and it came back fine. And she looked at it for like 1 minute and just said its okay. He was going to bed tonight and got back up and said it hurt so we went to the bathroom and I looked and it was extremely red and swollen again. What could this be!?! We just moved and I don't have a doctor yet!! So if you live near Kokomo Indiana and can refer me to a good pediatrician or just family doctor please do so I can get him in soon!
