Women with skin ulcers at the labia should go to a regular hospital to see a specialist for routine leucorrhea, skin tissue biopsy, venereal disease and other related examinations to clarify the cause of the disease before treating it. If the ulceration is caused by inflammatory gynecological diseases that lead to abnormal leucorrhea and repeated irritation of the skin at the labia, it should be treated with drugs such as metronidazole and potassium permanganate lotion. If the skin ulcers at the labia are caused by immune diseases such as leukoaraiosis, they need to be treated with glucocorticoids and immunosuppressive drugs. If the skin ulcers at the labia are caused by sexually transmitted diseases such as venereal disease and AIDS, you should go to a regular venereal disease specialist to receive symptomatic treatment according to the severity of the disease. In addition, you should pay attention to personal hygiene and cleanliness, wash and change your underwear regularly, and choose loose underwear to avoid repeatedly rubbing the affected area, otherwise it is not conducive to the healing of the ulcer surface.
