I am 22 years old female. I am suffering from menstruation cramps from the past 6-7 years. Every month I experience pain starting about 8-9 days before the due date of monthly menstruation in back, abdominal regions and inner thighs and at time of menstruation I am having unbearable pain in the back, abdominal regions, inner thighs, head ace and some months I also experienced vomiting. I also pooped a lot in periods and my pain relievers stopped working anymore. I am having great difficulty in doing my everyday work in these times. I have normal bleeding but unbearable pain in my monthly menstruation.
