Menstrual pain or menstrual cramps are sharp pains in a woman’s lower abdomen that occur when her menstrual period begins and may continue for 2-3 days.
Menstrual pain can range in severity from a mild annoyance to severe pain that interferes with normal activities.
The main cause of discomfort from menstrual pain comes from the uterus that makes chemicals called prostaglandins. These chemicals stimulate the uterine muscles to contract; therefore, women who have high levels of prostaglandin will experience more intense contractions of their uterus and more pain. Other menstrual type pain can be caused by conditions of the reproductive tract, such as harmless benign growths, infections, abnormal pregnancy, ovarian cyst, narrow cervix, and among other causes.
