Most women with itchy labia need to consider vaginitis, but other conditions such as vulvar skin diseases, pubic lice, and allergies to sanitary napkins or underwear can also cause itchy labia. Itching in the perineum is uncomfortable and some symptoms are severe and can affect daily life. If this symptom occurs, you should go to the hospital for a gynecological examination. The gynecological examination is mainly to understand the condition of the vulva skin, and also to see the state of the cervix and vagina, and also to take the white belt for a white belt test. The final treatment will be based on the results of the examination and the use of symptomatic medication, and the usual attention to perineal hygiene.
