Provoked vestibulodynia (vulvar vestibulitis)

[Sommer]

Provoked vestibulodynia (vulvar vestibulitis) is increased sensitivity to pain at the opening of the vagina (vestibule), making even gentle touch or stimulation painful.
Provoked vestibulodynia is the most common cause of superficial pain that is felt when sexual intercourse is attempted or is occurring (dyspareunia—see Dyspareunia). It occurs when the penis (or a dildo) enters the vagina or moves. The pain starts immediately, lessens when the penis stops moving, and resumes when the penis moves again.
Doctors are not sure why it happens, but the nerve pathways that conduct pain signals from the vulva and the parts of the brain that process those signals are physically changed (remodeled) and become more sensitive. As a result, touch that normally would seem mild is perceived as very painful. Muscles in the pelvis may also be tight, increasing pain. After intercourse, women may have a burning sensation in the genital area or during urination.
Having a genital yeast (candidal) infection that recurs may make provoked vestibulodynia more likely to develop or worsen.
Provoked vestibulodynia is considered a chronic pain syndrome. That is, the pain tends to remain, often for years unless treatment relieves it. It occurs whenever pressure is put on the area around the vagina
