after rotator cuff surgery i used narcotics for 3 days, becoming constipated. i used dulcolax 1 twice daily, then 2 twice daily, then 3 twice daily over 3 days before i had a bowel movement. however, at that point the stomach cramps were bad, the diarrhea persistent -- 6 movements over 2 days, i had chills and sweats with fever to 100, and felt listless, achey, and weak. can this be attributed to the dulcolax?
