Is waist acid normal during menstruation

During menstruation, if the symptoms of backache are mild, it may be a symptom associated with menstruation, which can be considered as a normal phenomenon. During menstruation, backache, if the symptoms are serious, affecting learning, life and work, is considered a manifestation of dysmenorrhea. Dysmenorrhea is divided into primary and secondary dysmenorrhea. Primary dysmenorrhea refers to dysmenorrhea without organic diseases of reproductive organs. It is caused by increased prostaglandin content in endometrium during menstruation. Increased prostaglandin can cause excessive contraction of uterus and vascular contracture, thus causing uterine ischemia and hypoxia. Secondary dysmenorrhea refers to dysmenorrhea secondary to pelvic inflammatory disease, endometriosis, adenomyosis and other diseases. Both primary dysmenorrhea and secondary dysmenorrhea belong to abnormal conditions.
