A small crack in the vulva can be treated by applying ointment under the guidance of a doctor. A small cracked vulva is considered to be a break in the skin, so you need to apply an appropriate disinfectant to the vulva area for cleaning to prevent infection from causing unnecessary trouble. In addition, you can apply erythromycin and other ointments, which can play a very good anti-inflammatory effect. You can also use the right amount of potassium permanganate to take a sitz bath every night before going to bed, not only to sterilize but also to ensure the cleanliness of the vulva area. When the vulva appears fissures should first suspend sexual life, to avoid making the fissures bigger and more painful phenomenon. You should also change your underwear regularly and don’t wear particularly tight underwear to prevent the vulva area from not being breathable which is not conducive to the recovery of the fissure. If the fissure is not particularly large, the fissure will recover on its own after using anti-inflammatory creams. You should first wash your hands during the use of the medication and then apply it to the vulva area to prevent bacterial infection.
