Trauma: If the patient’s local stimulation by external force causes rupture of mucosal blood vessels in the vagina or tissue damage, obvious pain, vaginal bleeding and other discomforts will occur. 2. Inflammation: If the patient has gynecological inflammation such as cervicitis and vaginitis, the pain and discomfort will be obvious because the local tissues are congested and edematous under the stimulation of inflammatory factors. 3. Endometriosis: If the ectopic endometrium is planted in the rectum and uterus, it will cause abdominal pain during menstruation or localized pain during sex. 4. Malignant tumors: for patients with malignant tumors such as cervical cancer and vaginal cancer, due to the rapid growth of cancer cells, insufficient blood supply to the local tissues will lead to necrosis of local tissues, which will result in local pain and discomfort. For patients with pain in the vulva, it is recommended to go to the gynecology department of regular hospitals to improve the ultrasound, blood routine, leukorrhea and other related examinations, and then take active treatment under the guidance of doctors after clarifying the cause of the disease.
