2. Iatrogenic factors. Women with vulvar pain often have a history of using external drugs many times. Because the protective barrier function of the cuticle of female vulva skin is not as good as that of other parts of the skin, vulvar irritation caused by external drugs is more common. Stimulation will not be the cause of the initial symptoms, but it may prolong the symptoms related to vulvar pain.
3. Psychological and sexual psychological factors. Women with vulvodynia will have obvious psychological and sexual psychopathy, but whether they can form symptoms is still controversial. During sexual intercourse, women will lack sexual arousal, reduce lubrication, and form vulvar vaginal stimulation, while periodic vulvar pain symptoms can produce vulvar pain.
