Vulvitis is caused by irritation from menstrual blood and vaginal secretions, or lack of attention to local cleanliness, among other reasons. Additionally, friction of skin and mucous membranes, local moisture, and poor breathability can lead to itching, pain, and burning sensations in the vulvar skin and mucous membranes. In the acute phase, there may be congestion, swelling, and erosion seen in the vulva, sometimes with scratch marks. The general treatment principle is to eliminate the cause, improve local hygiene, and keep the vulvar area clean and dry. Clean the vulva daily and keep the area dry.
