Vulvodynia is a chronic pain syndrome that affects the vulvar area and occurs without an identifiable cause. Symptoms typically include a feeling of burning or irritation. The exact cause is unknown but is believed to involve a number of factors, including genetics, immunology, and possibly diet.〔 Diagnosis is by ruling out other possible causes.〔 This may or may not include a biopsy of the area.〔 Treatment may involve a number of different measures; however, none is universally effective, and the evidence to support their effectiveness is often poor.〔 Some of these measures include improved vulvar care, dietary changes, medications, counselling, and, if conservative treatment is not effective, surgery.〔 It is estimated to affect up to 16% of women.〔 ==Signs and symptoms== Pain is the most notable symptom of vulvodynia, and can be characterized as a burning, stinging, irritation or sharp pain that occurs in the vulva and entrance to the vagina. It may be constant, intermittent or happen only when the vulva is touched, but vulvodynia is usually defined as lasting for years. Symptoms may occur in one place or the entire vulvar area. It can occur during or after sexual activity, when tampons are inserted, or when prolonged pressure is applied to the vulva, such as during sitting, bike riding, or horseback riding. Some cases of vulvodynia are idiopathic where no particular cause can be determined. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「vulvodynia」の詳細全文を読む スポンサード リンク
