Most women experience mild lower abdominal and lumbosacral discomfort when they have their periods or before and after their periods, which usually does not affect their life or work and is normal. Dysmenorrhea refers to painful symptoms during menstruation that are obvious and interfere with normal life. It is a symptom in itself, not a disease, but it means that one may suffer from gynecological diseases. Dysmenorrhea is very common, according to a survey of 71,746 women in 1980 in China, about half of the women had different degrees of dysmenorrhea, of which the more serious ones accounted for 13%. It is customary for doctors to classify dysmenorrhea as mild, moderate or severe. Mild dysmenorrhea means that the pain interferes with life or work, but is tolerable and sometimes requires a break. Moderate means that the pain needs to be relieved with painkillers. It is severe if medication does not work and pain relief injections are needed to stop the pain. Dysmenorrhea can be divided into primary dysmenorrhea and secondary dysmenorrhea by nature. The former refers to dysmenorrhea that occurs within six months to one year after the first menstrual period. This type of dysmenorrhea is more common and occurs mostly in unmarried young women. Some cases of dysmenorrhea are severe, but they do not usually mean that there is gynecological disease. If the gynecological examination is normal, the use of some pain-relieving drugs or treatment with herbs can mostly be effective. Primary dysmenorrhea is often significantly reduced or disappears after childbirth. However, in recent years, scholars at home and abroad have found that women with primary dysmenorrhea are prone to endometriosis later. Therefore, these women should be examined regularly. Secondary dysmenorrhea refers to women who begin to develop it several years after the first menstrual period. This type of dysmenorrhea is usually caused by gynecological diseases and should be promptly examined by a gynecologist. Diseases that can cause secondary dysmenorrhea include endometriosis, adenomyosis, uterine fibroids, pelvic inflammatory disease, etc., of which the first two are the most common. Sometimes intrauterine devices (IUDs) can also cause dysmenorrhea. Primary dysmenorrhea is mostly treated with Chinese herbal medicine or proprietary Chinese medicine, such as Wuji Baifeng Oral Liquid, Yue Yue Shu, Dahuang Sting Worm Pill, and Prosthodontic Punch. More serious cases can take some western medicine for pain relief, such as painkillers, fenbid, ibuprofen, keflex, etc. If that doesn’t work, you can also take soothing medicine. If that doesn’t work, you can also take Xumefan or intramuscular injection of Dulcolax, etc. However, these drugs have addictive properties and should not be used frequently. Secondary dysmenorrhea is usually caused by gynecological diseases. In addition to pain relief treatment, you should try to identify the cause and provide effective treatment for the original disease.
