Dysmenorrhea is a disease that occurs before, during and after menstruation and is mainly characterized by pain in the small abdomen and a feeling of swelling, and is mainly treated symptomatically. Some patients have different manifestations of dysmenorrhea. Some patients have pain in the lumbosacral area, and if it is mild and does not affect normal life, it is usually not treated and warmth is the main concern. If it is heavy and unbearable and affects normal life, it needs to be checked what exactly is the cause. In terms of the cause, there are primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea has no obvious organic lesions and is mainly related to high prostaglandins in the body, so warmth and pain relief are the main solutions. Secondary dysmenorrhea is caused by lesions in the pelvic organs, mostly endometriosis and adenomyosis, and the cause and specific lesions need to be determined. In short, after the occurrence of dysmenorrhea, the main principle is to keep warm, and at the same time, according to the specific cause of the disease, take symptomatic treatment, that is, pain relief.
