Hi,
Welcome to ehealthforum,
The itching could suggest possibility of infection, dryness, skin conditions etc. It is difficult to comment on the exact cause for your symptoms without examining you. You should consider visiting your doctor/gynecologist for further evaluation and assistance. Treatment as appropriate (based on examination and investigations results) would be started to help you control your symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. 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, get your partner also treated simultaneously to prevent chances of re-infection and avoid having intercourse while being on the treatment. Avoid unprotected intercourse.
Take care.
