A fever paired with severe abdominal pain days after trauma points to an intra-abdominal infection, most commonly a developing peritoneal abscess. After injury, contamination or tissue injury can lead to a localized collection of pus that slowly forms over a day or two; this abscess then causes fever and increasing abdominal tenderness as infection progresses. In trauma, this scenario fits the timeline and symptoms better than other possibilities: splenic rupture typically presents immediately after impact with possible shock, a retroperitoneal bleed often shows back or flank pain with signs of bleeding, and bowel obstruction presents with vomiting and distension rather than fever being the primary feature. So the combination of fever and delayed abdominal pain after trauma most strongly suggests a peritoneal abscess.
