There are many reasons for vulva ulcer, such as virus, bacteria, fungal infection, and gynecological inflammation, which stimulate skin damage and may lead to ulcers. In addition, if the female body estrogen level is relatively low, leading to the vulva skin and mucous membrane is relatively fragile, the pathogen is relatively easy to invade. All these reasons can cause vulva ulcer. If there are patients with vulva ulcer, they must go to the regular hospital for inspection in time. The professional doctor gives the symptomatic treatment plan, and the patient must treat according to the doctor's advice.
