If a woman has a very itchy vulva, but there is nothing wrong with her leukorrhea, it is important to consider that the vulvar skin itself is the cause. In a small number of women, it may be caused by pubic lice growing in the pubic hair. If the itchy vulva is accompanied by changes in vulvar pigmentation, it is important to consider vulvar dystrophy, which can only be diagnosed by a biopsy of the hypopigmented part of the vulva, since there is no way to confirm the diagnosis with an ordinary examination. If it is considered to be vulvar dystrophy, you can consider using progesterone ointment or Fosfomycin ointment for topical application to stop the itching. For women with particularly severe itching symptoms, a localized injection of tretinoin solution may be needed to relieve the itching.
