A 60-year-old male presents with acute onset of lower left quadrant pain, constipation, and low-grade fever. The patient has a history of recurrent similar episodes. What could be the issue and what steps should be taken next?
Given the patient's age, recurrent similar episodes, and presentation with left lower quadrant pain, constipation, and low-grade fever, a probable diagnosis is diverticulitis. This diagnosis can be confirmed with a CT scan, which is the imaging modality of choice. Treatment typically involves antibiotics, bowel rest, and, in some cases, hospitalization.
