If the patient has pruritus of the foreskin, it may be caused by balanitis of the foreskin. If the symptoms are not particularly serious, warm water washing can be used to alleviate the symptoms. If there are signs of redness, swelling and exudation in the local area, use drugs to smear under the guidance of the doctor, and take antibiotics orally. If the symptoms of pruritus, redness and swelling of the foreskin occur repeatedly, it should be clear whether there is the appearance of redundant foreskin. If necessary, circumcision can be used for treatment. It is suggested that patients should pay more attention to local cleaning in their daily life, and avoid cleaning glans with alkaline lotion to prevent itching. The diet should be light, and you can drink more boiled water.
