question: I have severe abdominal pain and cramping that sometimes leaves me doubled over and having difficulty standing up straight. I have episodes of nausea and vomiting. I have a lot of gas. My bowel movements have changed. I spent 3 days in hospital 2 weeks ago and was diagnosed with paralytic ileus. Abdominal pain has continued though. I have several good days with no symptoms and then the above symptoms return, sometimes accompanied by headaches and fatigue.
