In addition, in order to allow menstrual blood to be discharged smoothly, women will secrete a certain amount of prostaglandins from a few days before menstruation to during menstruation. If prostaglandins are secreted too much, it will cause spasm of the uterine smooth muscle, which will radiate to the waist and cause waist pain.
