Vulvodynia means ongoing pain in the vulva (the female genital area) when there is nothing abnormal to see and no known cause for the pain.
Vestibulodynia is a term used for pain arising at the entrance of the vagina, in the area known as the vestibule (the area of the openings to the vagina and the urethra), when any pressure, be it touch or friction, is applied. It is also called localised vulvodynia.
Vulvodynia, whether it is generalised or localised, may be described as provoked (caused by touch) or spontaneous (occurring without touch as a trigger).
Many conditions affecting the vulva can be painful (e.g. infections such as thrush or herpes, as well as skin diseases such as eczema). In vulvodynia, pain is felt in the vulva when there is no obvious visible cause for it and other diagnoses have been ruled out by examination and investigation.
