Vulvar disorders are conditions that cause pain in or around the female genitals (vulva). Some (but not all) may include visible skin conditions. Vulvar disorders may be caused inflamed nerves, allergies, skin diseases, diabetes or infection or the cause can be unknown. The pain may be in the vulva, or it may reach to the rectal area or legs. Vulvar pain can flare up with activities such as sitting on a bicycle, having sex or inserting a tampon.
