The pain of menstruation is generally referred to as dysmenorrhea, which is categorized into primary dysmenorrhea and secondary dysmenorrhea, and can be relieved by strengthening general conditioning measures and taking medication as prescribed by the doctor. 1. Primary dysmenorrhea: Generally, you can relieve the pain by applying hot water bags to the abdomen, drinking a moderate amount of hot water and listening to soothing music. If the above measures are not effective and the abdominal pain is severe, you can take prostaglandin synthase inhibitors, such as ibuprofen and diclofenac sodium, as prescribed by your doctor to relieve the discomfort. Some women can take intramuscular injection of progesterone or oral methylhydroxyprogesterone to inhibit uterine contractions and relieve pain, and can also seek medical treatment with transcutaneous electrical nerve stimulation. 2. Secondary dysmenorrhea: If it is caused by IUD damage or infection, the IUD can be removed. If it is caused by endometriosis, oral contraceptive pills or gonadotropin-releasing hormone agonists such as leuprolide and goserelin can be used as prescribed by the doctor, and progesterone such as medroxyprogesterone acetate and medroxyprogesterone can be applied as well. Surgical treatment is also available for severe cases. If it is caused by adenomyosis, non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin can be applied to relieve the condition as prescribed by the doctor, and surgical treatments such as lesion excision and endometrial removal can be carried out if necessary. If it is caused by large uterine polyps, it can be treated with hysteroscopic polypectomy, hysterectomy and other surgical treatments as prescribed by the doctor. It is recommended that people with dysmenorrhea consult a doctor for examination, so as to clarify the cause of the disease and then follow the doctor’s instructions to use medication, do not use drugs indiscriminately.
