When you have back pain due to aunt (menstrual) pain, you first need to identify the cause and treat the back pain during menstruation. After identifying the cause, the pain can be relieved clinically by means of general treatment, medication, and so on. However, if the dysmenorrhea is caused by other diseases such as endometriosis, it is necessary to treat the primary disease by means of surgical treatment, so as to relieve the symptoms of dysmenorrhea. 1. General treatment: The symptoms of dysmenorrhea can be relieved by keeping warm and applying hot compresses. If dysmenorrhea is caused by psychological factors such as poor mood and emotional tension, the pain can be relieved by relaxation and distraction. 2. Medication: If the pain is not relieved by general treatment, primary dysmenorrhea can be relieved by taking non-steroidal anti-inflammatory drugs such as ibuprofen extended-release capsules, naproxen, ketoprofen and so on under the guidance of a doctor. If dysmenorrhea and back pain are caused by gynecological inflammation, antibiotics are needed for anti-infection treatment. If the dysmenorrhea and back pain are caused by endometriosis or adenomyosis, you can take some hormonal drugs, such as medroxyprogesterone and dienogest. 3. Other treatments: In the case of secondary dysmenorrhea caused by endometriosis, for example, in addition to general treatment and medication, surgical removal of the diseased tissue can also be used to alleviate the pain and other symptoms. There may be other reasons for menstrual cramps and back pain, so it is recommended to consult a doctor for a clear diagnosis and standardized treatment under the guidance of a physician if necessary.
