If the phimosis of a child has local inflammation, redness, swelling, and itching of the foreskin, it can be treated with local antibiotics, such as erythromycin ointment, or 3% boric acid solution for soaking. If the child phimosis appears repeated prepuce balanitis, it is best to recommend surgery. The foreskin is narrow, and the foreskin cannot be turned up to expose the penis head. Because the foreskin tightly wraps the penis head, dirt is easy to form under the foreskin, which forms balanitis of the foreskin. In severe cases, purulent secretions can also appear at the urethral orifice. (The use of drugs should be conducted under the guidance of doctors)
