Women who experience pain in the lower abdomen after menstruation are called dysmenorrhea. Dysmenorrhea is divided into primary dysmenorrhea and secondary dysmenorrhea. In the case of primary dysmenorrhea, you mostly need to consider taking painkillers for symptomatic pain relief treatment during dysmenorrhea. If the pain is not severe, you can take prolotherapy pills and Yuanhu pain relief tablets. For women with more pronounced pain, you can take ibuprofen extended-release capsules for symptomatic pain relief treatment. If the pain is particularly severe, you can consider intramuscular pain injections for pain relief, such as intramuscular 654-2. Since symptomatic pain relief during dysmenorrhea does not cure the dysmenorrhea completely and it will appear again at the next menstrual period, women should have long-term conditioning treatment during non-menstrual periods. If a woman has secondary dysmenorrhea due to adenomyosis, endometriosis, etc., she should consider placing levonorgestrel intrauterine device for adenomyosis in addition to symptomatic pain relief in the near future.
