Dysmenorrhea is generally abnormal. Under normal circumstances, if menstruation involves ovulation, there may be slight discomfort in the lower abdomen during menstruation, which is considered normal. If dysmenorrhea is present and tends to worsen over time, this condition usually indicates the possibility of endometriosis. In such cases, it is essential to visit a hospital for a color ultrasound and a CA125 blood test to confirm if the pain is caused by endometriosis, and treatment should be based on the diagnostic results. Furthermore, if dysmenorrhea is caused by a cold uterus, symptoms might include pain accompanied by a cold sensation in the lower abdomen and cold extremities. In this case, it is typically necessary to take medicine that warms the meridians, dispels cold, and alleviates pain in the uterus. If dysmenorrhea is due to qi stagnation and blood stasis, one can take medicine that promotes blood circulation, removes blood stasis, and relieves pain in the meridians. Therefore, dysmenorrhea is not normal.
