thank you for posting your query in healthcaremagic.com.... vaginal and adjacent area itching is somewhat normal prior to periods....happens to many females....so not a case of worry.... also vaginal itching can be due to many other causes like urinary tract infections, bacterial or fungal infections of the vagina, dermatitis etc.... answer a few questions - is it painful? do you have vaginal discharge? is there any swelling or ulcer/sore? is your partner experiencing similar problem? you can get back to me with the answers for further management and you can also visit a GYNAECOLOGIST for the same.... hope that was helpful.... regards..
