Hello, my 9 year old son is having pain on his belly button and the tip of his penis at the same time. This pain happens while he is peeing also. This is the second time he has experienced this in a 3 month period. It has never happened before these two times. I checked the area of his penis and there s no redness or swollen area. I ve tried googling this and it seems a lot of boys have experienced this but could not find a diagnose.
