There are many clinical causes of dysmenorrhea accompanied by fever, including painful stimulation and reproductive tract infection, the former can often be relieved on its own with the end of menstruation, while the latter usually requires medication to make the fever subside. 1. Painful stimulation: the stimulation of prostaglandins in women during menstruation can lead to abdominal pain, and some women have more severe dysmenorrhea, which may lead to an increase in body temperature due to the painful stress response. The patient can take pain medication, and the temperature can gradually return to normal after the menstrual pain is relieved; 2, reproductive tract infection: if menstrual pain occurs, and the measurement of body temperature is found to be abnormal, consider the possibility of infection, such as chronic pelvic inflammatory disease, mostly in sexually active women of childbearing age, need to actively carry out anti-infection treatment, such as oralloxacin or levofloxacin or cephalosporins The treatment should be accompanied by metronidazole to avoid further spread of the infection. During menstruation, if there are symptoms of dysmenorrhea, painful stimuli can be relieved by increasing warmth, applying hot compresses to the abdomen, moderate massage, and adequate rest. If the patient has frequent dysmenorrhea with fever, she should go to the gynecology department of a regular hospital for gynecological examination and examination of ultrasound, blood count, C-reactive protein, calcitoninogen and other infection indicators to clarify the cause and then treat the problem.
