Salt water washing is not recommended for women who experience itching of the vulva. The main cause of vulvar itching is usually due to various types of vaginitis, vulvodynia and vulvar skin lesions. Washing the vulva with salt water can only provide short-term relief of the itching symptoms, but cannot treat the root cause. A gynecological examination is needed for vulvar itching. By doing a gynecological examination, you can understand the nature of the leukorrhea, but also understand the specific type of vaginitis. If it is clear that it is caused by vaginal inflammation, you can carry out symptomatic treatment according to the results of the examination; if it is caused by inflammation of the vulva, you can use some topical rubbing medicine; if it is caused by allergies, you should change your underpants and sanitary napkins and so on in a timely manner.
