Vaginal pain in women during menstruation: 1. It may be caused by rapid blood circulation in the pelvic area during menstruation and endometriosis, which can lead to vaginal pain. 2. It may also be caused by vaginitis and the stimulation of the vaginal wall by menstrual blood. 3. It may also be caused by cysts and inflammatory masses in the vagina. If a woman has mild vaginal pain, she can rest and apply hot compresses to her lower abdomen to make the menstrual blood flow smoothly and not to overexert herself for a while. If the vaginal pain is obvious and accompanied by vulvar itching, women can wash their vulva with cleanser 1-2 times a day, wear loose underwear and change sanitary napkins regularly. After the menstrual period, go to the hospital to review the white belt routine and gynecological ultrasound to confirm the diagnosis.
