See your health care provider and ask about other vulvar skin conditions, like vulvar lichen sclerosus, that can cause chronic itching. Most women with lichen sclerosus go undiagnosed for years because the itching or pain can be severe with no obvious skin changes in the early stages. If your gyncological health care provider is not comfortable with vulvar biopsy and diagnosis of vulvar conditions, ask for a referral to a specialist.
