Irritation of the sensitive vaginal tissue can cause severe vaginal itching in women. Females who experience persistent, intense vaginal itching, especially if this symptom occurs in conjunction with unusual vaginal discharge, should seek medical care. A doctor may prescribe an antibiotic or antifungal medication to eradicate the cause of the itching.
Vaginal Yeast Infection
One of the most common causes of severe vaginal itching is a vaginal yeast infection. This type of vaginal infection occurs as a result of vaginal overgrowth of a naturally occurring fungus called Candida albicans. Women who are sexually active or use certain types of antibiotics or contraceptive methods are at an increased risk of developing vaginal yeast infections. Intense vaginal itching due to this infection can be accompanied by thick, white vaginal discharge, uncomfortable urination or pain during sexual intercourse. Women who develop any of these symptoms should contact a doctor for further evaluation and care.
Pubic Lice
Pubic lice, also called crabs, can cause intense vaginal itching in affected women. Symptoms of itching arise when lice attach to pubic hairs in the vaginal region and irritate and inflame the surrounding skin. Affected women can also experience anal itching, fever, malaise or irritability. Pubic lice can be transmitted through intimate contact with an infected person or contact with contaminated clothing, toilet seats, bedding or furniture.
Chemical Allergy
An allergy to latex, spermicides or chemical irritants, such as soap or laundry detergent, can induce severe vaginal itching in certain women. Females who are allergic to latex can develop intense vaginal itching after having sexual intercourse with a partner who uses a latex condom. Sensations of itching can persist for several hours or days following vaginal exposure to a chemical irritant, but symptoms progressively subside once a woman is no longer in contact with the irritant. Severe latex allergy symptoms, such as swelling, hives or breathing difficulties, can be life-threatening and require immediate medical attention.
Additional Causes of Vaginal Itching
Mild to moderate vaginal itching can also arise as a consequence of vaginal infections, sexually transmitted diseases, hormonal changes, douching, emotional stress, menopause or certain type of medical therapy, such as pelvic radiation. Women who experience mild or sporadic vaginal itching, especially in conjunction with pelvic pain, flu-like symptoms or unusual vaginal discharge or odor, should seek care from a physician.
