Menstrual cramps can be intense and leave one feeling groggy and under the weather. If you must have a busy or productive day and cannot afford to take a break on the first two days of your period, you may want to find a way to ease the discomfort and have an easier time dealing with the cramps.
Mayoclinic describes these cramps as throbbing pains in the lower abdomen. The severity of the pain may vary during the cycle, going from intense spasms to dull, constant pain.
