During menstruation, due to uterine contractions and discharge of menstrual blood, it is normal to have mild back pain and abdominal pain, but if the pain is severe, it should be considered dysmenorrhea. Dysmenorrhea is caused by prostaglandins synthesized by the uterine lining leading to severe contractions of the uterus. If the pain is not serious, you need to pay more attention to keep warm during menstruation, you should avoid all cold and indigestible and stimulating food can be relieved. If the pain is severe and prolonged, you can't rule out some gynecological diseases, such as endometriosis, adenomyosis, fibroids and pelvic inflammatory disease, which can also aggravate the symptoms of dysmenorrhea, and you need to go to the hospital to confirm the diagnosis, and then consider the treatment. e
