Menstrual pain or cramps are pains in your lower abdomen that happen when your menstrual period begins (or just before). This pain may continue for 2 to 3 days. Cramps may be throbbing or aching, and they can be dull or sharp. Symptoms can range from a mild discomfort to serious pain that interferes with your normal activities.

Menstrual cramps are the leading cause of absenteeism in women younger than 30. Although over half of people who have menstrual periods feel some discomfort, 10% are temporarily disabled by symptoms.
