If you are being treated for a yeast infection and have gotten no relief, you must go back to your doctor. You may actually have vulvar vestibulitis. Like a yeast infection which doesn't always cause a discharge, vulvar vestibulitis causes swelling and redness of the vulva. Urination may be painful. Doctors believe the condition stems from hyperactive pelvic nerves that cause muscle spasms. The spasms trigger reactions that lead to the release of histamines into the skin, causing pain and swelling. With medication it can be controlled. General symptoms of yeast infection include a change in the amount, color, odor, or consistenc the discharge, itching, painful urination. It can be caused by excessive douching, strong soaps or perfumed feminine hygiene products, wearing tight pants or jeans, even bicycling. Antibiotics, which kill protective bacteria, stress, pregnancy, diabetes, and birth control pills, as well. Bacterial infections may go away by itself in 3 to 4 days. Make sure that the cause of the yeast infection is not a forgotten tampon. Over-the-counter antifungal creams (gyne-lotrimin, monistat 7) are available to treat yeast infection.
