Patient's question:
2012 found? It's awful pain when the period comes! Can't use strength... Go to Changle HospitalDoctor's answer:
Some congenital or acquired diseases that cause poor drainage of menstrual blood, such as hymen atresia, vaginal atresia, cervical stenosis, uterine malformations (especially rudimentary horn of the uterus), and severe retroflexion of the uterus, can lead to poor drainage or retention of menstrual blood, causing it to flow back into the pelvic cavity, implant, and develop into endometriosis. Therefore, these conditions should be examined and treated early.
