Female menstruation refers to menstruation and the pain experienced by every woman during menstruation is different and cannot be generalized. Some women have no pain during menstruation, most women experience mild pain that can be tolerated, while some have severe pain that is unbearable. Women’s menstrual pain is mostly primary dysmenorrhea, caused by the uterus contracting to expel menstrual blood, which is sensitive to prostaglandins. Mild pain can be left untreated, and if the pain is strong, prostaglandin inhibitors can be taken to stop the pain. Some women suffer from secondary dysmenorrhea due to organic lesions in the pelvic area. The pain is so severe and unbearable that they may have symptoms such as pallor, cold limbs, or even fainting, which need to be treated with oral medication or surgery after the cause is clearly defined in order to relieve the dysmenorrhea. Therefore, every woman feels different pain during menstruation and should be treated if necessary.
