What is the reason for the pain in the head of the penis when the foreskin is retracted?

Patient's question:

Patient Gender: Male
Why does there be pain in the glans when the foreskin is retracted?

Doctor's answer:

Penile phimosis refers to a condition in which the penis's skin covers the glans, preventing it from being fully exposed. It can be further divided into true phimosis and false phimosis. True phimosis is when the glans cannot be fully exposed even when the penis is erect. False phimosis, on the other hand, is when the glans cannot be fully exposed at rest but can be fully exposed when the penis is erect. Phimosis, in contrast, refers to a condition where the foreskin completely covers the glans, leaving the glans unable to be exposed at any time.
Considering the prevention of infection and improving sexual life, it is advisable to promptly undergo a circumcision procedure at a local reputable urology hospital to avoid improper treatment and infection in small clinics.
