Hi,
Welcome to ehealthforum,
The itching and soreness could suggest infective causes, dryness, inflammation etc. The exact cause can only be made out after careful evaluation. Visit your doctor/gynecologist at the earliest 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 to control the symptoms. Consider being in regular follow-up and monitoring of your treating doctor/gynecologist and report any abnormal/new 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.
Take care.
