Itching of the vulva may be caused by vaginal inflammation. If there is vaginal inflammation such as Candida infection, trichomonas infection, mycoplasma infection, chlamydia infection, etc., it may cause itching of the vulva. Vulvar itching is not only caused by local inflammation of the vagina, but may also be caused by lesions of the vulva itself, such as dermatitis of the vulva like eczema and seborrheic dermatitis, which may lead to local itching of the vulva. In addition, local allergic reactions caused by the use of sanitary napkins can also cause severe itching, and vulvar dystrophy can result in localized skin whitening of the vulva and can lead to localized itching. Therefore, itching of the vulva is clinically caused by multiple etiologies. It is recommended to go to the hospital in time to do the corresponding examination and make a preliminary diagnosis after the examination and then give treatment.
