Dysmenorrhea is a very common clinical condition, which is a cramping pain in the lower abdomen that occurs every month when a woman is menstruating before menopause, either during puberty or during marriage. In many people, the pain is only mild and not within the range of dysmenorrhea. It is only when you need to take painkillers or need other help to stop the pain that it is called dysmenorrhea. Dysmenorrhea is divided into primary and secondary. Primary dysmenorrhea is basically in adolescence, and pain is more common in adolescence. For patients during marriage and childbirth, especially postpartum, dysmenorrhea is secondary to dysmenorrhea. Both adenomyosis and chocolate cysts are classified as endometriosis and also belong to the scope of secondary dysmenorrhea. Chinese medicine believes that menstruation is related to the movement of the Qi and Blood, the Qi and Blood vessels, the Ren and Ren veins, and the meridians.
