Women with mild vulvar itching, mostly caused by chemical fiber underwear or pads, can wash their vulva with warm water, but try not to douche the vagina to avoid vaginal flora imbalance, change cotton loose underwear, avoid using pads for a long time or try not to use them, clean the vulva well and avoid spicy and stimulating diet. If vulvar itching is increased and vaginal discharge is observed, it is mostly a sign of vulvovaginal inflammation. If the vaginal discharge increases and is yellow with a fishy odor, it is mostly caused by bacterial vaginosis. If vulvar itching is accompanied by tofu-like leucorrhea, this is a typical sign of mycosis fungoides. If the leucorrhea is frothy with unbearable vulvar itching and a distinct foul odor, it is a sign of trichomoniasis. Each vaginitis has a different cause and treatment, so you should not use random medication or wash with lotion.
