If a woman has abdominal pain before each period and the pain is significantly worse after the onset of menstruation, it is considered to be a sign of dysmenorrhea, most likely caused by adenomyosis, or ovarian chocolate cysts that cause premenstrual pain. It is best to check the ultrasound to confirm the cause of menstrual pain in these women. If there is no organic disease in the uterine appendages, primary dysmenorrhea is considered. These women can go to the gynecology department of the hospital about a week before their menstrual period to take Chinese herbal medicine to regulate the treatment. Or take non-steroidal anti-inflammatory drugs during each menstrual period, which also have significant pain-relieving effects. For patients with secondary dysmenorrhea, surgical treatment should be considered to remove the cause.
