Hi,
Welcome to ehealthforum,
Vaginal/vulval itching suggests chances of infections (commonly seen around the time of periods), vaginal dryness (due to hormonal imbalances), skin conditions, etc. The exact cause can only be made out after careful evaluation. Visit your doctor/gynecologist for further examination and investigations to look for the underlying cause. Treatment as appropriate (based on the examination findings and investigation results) would be started to help you control the symptoms. Be in regular monitoring and follow-up of your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection.
Take care.
