When vulvar ulceration occurs, you should not rush to treat it first, you need to consult a doctor to confirm what causes it. For example, skin inflammation or eczema can lead to vulvar ulceration because this area is less breathable and usually easy to be moist, so if bacterial infection occurs, it is especially easy to have inflammation. If it is a local dermatitis or eczema, anti-allergy ointment, such as hydrocortisone ointment, can be given under the guidance of a doctor. If you have a history of impure sexual activity and vulvar ulceration, you also need to be alert to whether you are infected with syphilis spirochetes or genital herpes virus, and you need a sexually transmitted disease doctor to do the relevant examination and give the corresponding treatment measures according to the examination results for better results.
