The International Society for the Study of Vulvovaginal Disease (ISSVD) defines vulvodynia as chronic vulvar discomfort or pain, characterized by burning, stinging, irritation or rawness of the female genitalia in cases in which there is no infection or skin disease of the vulva or vagina causing these symptoms. Burning sensations are the most common, but the type and severity of symptoms are highly individualized. Pain may be constant or intermittent, localized or diffuse. Generalized Vulvodynia is the term used for the more diffuse symptoms whereas Vestibulodynia. (formerly known as vulvar vestibulitis) is when pain is more localized to the vestibular tissue at the entrance of the vaginal canal.
