Cramps usually begin one to two years after a woman starts getting her period. Pain usually is felt in the lower abdomen or back. They can be mild to severe. Common menstrual cramps often start shortly before or at the onset of the period and continue one to three days.
Premenstrual cramps happen when the body undergoes hormonal imbalances. These generally occur before menstruation cycles and are characterized by a range of physical and emotional symptoms. These cramps are a part of the group of symptoms experienced in PMS (premenstrual syndrome) where the body discharges menstrual fluids. As a result, the abdomen and back muscles experience additional stress that leads to cramping pain.
