[Vulvodynias].

VULVODYNIAS. Vulvodynia is a chronic pain. The distinction between so-called "provoked" vulvodynia and "spontaneous" vulvodynia allows a diagnostic and therapeutic orientation. "Provoked" vulvodynia responds to the mechanisms of hyperalgesia encountered in hypersensitization. The model is provoked vestibulodynia. The model of "spontaneous" vulvodynia is pudendal nerve neuralgia, whose mechanism is neuropathic pain. Other types of vulvodynia are due to peripheral sensitization or integrated into the central pelvic hypersensitization syndrome and the vulvodynia of myofascial syndromes and the clitorodynia. Finally, a specific place will be given to the persistent genital arousal disorder (PGAD). Understanding vulvodynia requires a good knowledge of the anatomy and the mechanisms of peripheral and central sensitization.
