Suggest Remedy For Constant, Severe Itching In Vagina

Hello Doc. from the past weeks I am having this problem with my private part. It feels itchy, and I can't control my self to scratch them, especially after I come home and I'm on the shower, I will scratch them till I feel no more itch. and every night I woke up that I feel itchy again and I have to scratch them again. Right now I'm on my period. I kept myself dry and clean because I can't stand being moist down there.
