The first is functional dysmenorrhea, which occurs in teenage girls and is caused by an increase in prostaglandins during menstruation, and can be treated symptomatically with ibuprofen, Yuanhu painkillers, mebendazole and other painkillers, or with Chinese herbal medicine. The second is dysmenorrhea caused by organic lesions, such as adenomyosis, gynecological inflammatory diseases, uterine developmental malformations, and so on. This condition requires differential diagnosis through gynecological ultrasound, hysteroscopy, laparoscopy, gynecological examination and other related examinations, and targeted treatment according to the specific situation. In the case of adenomyosis, intrauterine placement of the Mannorrhea ring or treatment with drugs such as leuprolide acetate can be chosen. If the uterus is malformed, it can be removed or orthopedic treatment can be performed depending on the specific case. In case of inflammatory disease, anti-inflammatory treatment with antibiotics is required.
