Itching in the vagina (itching of the vulva) depresses and irritates. The causes of itching in the vagina can be factors that lead to the occurrence of itching in the whole body or skin diseases (for example, psoriasis, red flat lichen). The cause may also be local: infection and vaginal discharge (eg, vulvovaginal mycotic); invasion (for example, scabies, pubic lice, pinworms).
