My three year old son suddenly developed bright red spots (like a cluster of dots) on the shaft of his penis, which we can only see when we stretch the skin out. He is circumcised, but we ve never really had a problem. The congregation of spots looked a lot like blood, so we were very concerned. Any idea what it might be?
Hidden development of red spots over genitalia suggest possibility of allergic reaction. Antihistaminic like CETIRIZINE will be helpful in resolution. If the symptoms persist then I suggest you to consult Pediatrician for further assessment.
