I want to know about paraphimosis

Paraphimosis happens when the foreskin has been pulled back behind the head of the penis and cannot be moved back into its normal position. This can cause swelling and reduce blood flow to the head of the penis. 

Paraphimosis is an emergency and needs urgent medical treatment

Your doctor will first try to reduce the swelling and gently move the foreskin back over the head of the penis.

If reducing the swelling is not possible, a small cut may be made in the tight ring of foreskin to release the pressure. Further treatment, including circumcision, may be recommended if there is a risk that the problem will happen again.

To help prevent paraphimosis, always move the foreskin back to its normal position after pulling it back.
