How to treat itching in the private area

Patient's question:

Male, 24 years old, no history of poor sexual life
A small patch at the back of the penis where the pubic hair grows started itching a week ago, followed by ulcers and pus discharge.
Later, I bought an antiseptic solution from a pharmacy and applied it to the affected area. At first, it started to form a scab, but in the morning, it would crack open again. Since it was growing in the pubic hair area, I shaved the hair off and used a bandage. However, the scab never formed.
I didn’t go to the hospital. Over the past two days, I’ve been applying the antiseptic solution to the area. I’ve stopped using the bandage, and now the pus discharge has stopped, and it’s starting to form a scab. I’m not sure if it will crack open again. What is this?

Doctor's answer:

Vaginal itching refers to a symptom caused by various gynecological diseases. The treatment of this condition primarily involves paying attention to menstrual hygiene, maintaining vaginal cleanliness, and promptly eliminating the underlying cause. Eu Shan ozone antibacterial agent can be used for treatment. This product has antibacterial effects on the skin, skin mucosa, and vaginal mucosa of women.
