My daughter, 54 years old, had abdominal surgery, two sections of large bowel removed, 7 days ago, she was receiving intraveinous pain meds, however, they were stopped on Tuesday evening and she has been in constant pain since. She is on liquids only and cannot tolerate anything other than ice or water. She has not passed urine for over 12 hours and I am worried. She is in constant pain and the pills are not helping with the pain, how can she get them to start intravenous pain meds again. She is over weight and this may be the problem, she should be ready to be discharged after seven (7) days.
