Well, vulvar itching is mostly located in clitoris and labia minora, and can also spread to labia majora, perineum and even perianal lesions. Often paroxysmal or persistent, generally aggravated at night. Unreasonable vulvar pruritus generally only occurs in women of childbearing age or postmenopausal women, and it affects the whole vulva. There are often the following reasons: (1) fungal vaginitis and trichomonal vaginitis are the most common causes of vulvar itching. Lice and scabies can also cause itching. Itching around anus and vulva caused by pinworm usually only occurs at night. (2) Chronic vulvar malnutrition is characterized by itching, accompanied by whitish vulvar skin. (3) Soaps, condoms, bromogeramine, etc. that are allergic to drugs or stimulated by chemical crystals. Contact dermatitis and itching can be caused by direct irritation or allergy. (4) Poor hygiene habits, not paying attention to the local cleaning of vulva, sebum, sweat, menstruation, vaginal secretions, and even urine and feces soaking for a long time can cause itching: rubber or plastic menstrual belts and airtight chemical fiber underwear during menstruation can cause itching due to damp heat stagnation; (5) Other skin lesions, abrasions, common warts, herpes, eczema and tumors can all cause vulvar itching. It may also be a systemic disease: diabetic jaundice, pregnancy and premenstrual vulvar congestion occasionally lead to vulvar itching and discomfort. Unexplained vulvar pruritus is very serious in some patients, but no obvious systemic or local causes can be found. At present, some people think it may be related to mental or psychological factors 1. Mycotic vaginitis 2. Vaginal trichomoniasis 3. Crab disease may also cause the symptoms you mentioned. I suggest you go to the dermatology department to find the reason, prescribe the right medicine, and wish you health!
