Why are some cramps so painful?
The difference between menstrual cramps that are more painful and those that are less painful may be related to a woman’s prostaglandin levels. Women with menstrual cramps have elevated levels of prostaglandins in the endometrium (uterine lining) when compared with women who do not experience cramps. The cramping sensation is intensified when clots or pieces of bloody tissue from the lining of the uterus pass through the cervix, especially if a woman’s cervical canal is narrow.
