The difference between vulvar itching and vaginal itching is that vaginal itching is caused by local inflammation of the vagina, mostly due to trichomonas or mycobacterial infections, accompanied by allergic phenomena, which can cause vaginal itching, while vulvar itching is not only due to vaginal inflammation, such as vaginal secretions flow to the vulva to stimulate the itching. In addition, localized lesions of the vulva can also cause itching, such as vulvar dystrophy can appear vulvar skin whitening and severe itching, such as vulvar eczema can also cause localized itching, and pubic lice of the vulva can also cause localized itching. Wherever the itch is, it is advisable to identify the cause and treat it.
