what can cause a dull menstrual like cramp pain on right side of pelvic area? . for the past 3 to 4 days i have been having a menstrual cramp like pain but it is only on the right side. it is not a severe pain but enough of pain that after 4 days it has worn me down and made it hard to do anything. i have taken perscription ibprofen i had left from my gallbladder surgery and it doesnt seem to help. if i put a heat pack on the area it helps but as soon as i get up and move around its right back to hurting again. im absolutley miserable. what can cause this?
