Hi, Thanks for posting in HCM. I understand your concern. After going through the description, it appears that your son could be having phimosis . It is narrowing of the opening of the foreskin so that it cannot be retracted. This results in swelling of the glans and penis. It would be better you could consult a Surgeon at the earliest and examined clinically. In case it is unable to be maneuvered, he may need to undergo circumcision. Hope the information provided would be helpful. All the best.
