A 67-year-old man presents with constipation that has been present for the preceding 2 days. He reports that he has had constipation in the past that resolved with the use of over-the-counter stool softeners, but this therapy has not worked with this episode. He has generalized abdominal pain that was mild initially but increased over the preceding day, which prompted his visit to the urgent care center. He describes the character of the pain as crampy and constant but intermittently worse. He reports that he has associated nausea and has vomited once but has not had diarrhea. No blood in the urine or stool, fever, chest pain or shortness of breath, or back pain.
