What causes external genital itching?

Patient's question:

Vaginal hyperpruritus

Doctor's answer:

Hello, vulvar itching refers to a symptom caused by various gynecological diseases, known in traditional Chinese medicine as "vulvar pruritus." The treatment of this condition focuses on paying attention to menstrual hygiene, maintaining vulvar cleanliness, and promptly eliminating the cause—treating the root rather than the symptom leads to health.
