i am a 10 year old boy and about 80lbs my height is 4 ft 4 and i have a lot of pain at the top of my penis.When it swells a little there is a ring that goes around the tip of it, that looks like a ringworm, than Im in constant pain,even when it goes down.I have been to Boston Children Hospital but as usual at the time I was in no pain, until the beginning of the school year, which has just begun.
