If you have a falling sensation in the anus every time you menstruate, and you don’t have lower abdominal pain in your daily life, and you don’t have lower abdominal pain during intercourse, this is often due to an abnormal position of the uterus. For example, if the uterus is in a retroflexed and tilted position, the uterus will be congested during menstruation, and the pelvis will be congested, and the retroflexed and tilted uterus will stimulate the posterior peritoneum, causing a feeling of falling in the anus, and causing pain in the lumbosacral region. It is recommended to rest properly during menstruation. Resting on the bed can correct the retroflexion and retroversion of the uterus, so that the menstrual blood can flow more smoothly, which in turn reduces the feeling of anus falling. In addition, you can also do moxibustion to promote local blood circulation, will also reduce the occurrence of this situation.
