What should I do if my child's foreskin is swollen and red and cannot be retracted?

Patient's question:

Patient Age: Seven years
Duration of current illness and persistence: 4-5 days
Current general condition: Swollen and red, unable to lift
Medical history: None
Previous diagnoses and treatment history and outcomes: None
Ancillary tests: None
Other: None

Doctor's answer:

Washing the baby's foreskin, twice a day, it will definitely heal within three days. If the foreskin cannot be retracted, it's okay. During washing, retract it as much as possible. Doing these actions frequently will help the foreskin retract without the need for surgery.
