A page comes in from downstairs—another admission. A 41-year-old postal worker in bed 22, presented with severe back pain and needs pain control and a physical therapy evaluation. Three weeks ago, he was lifting a box when he felt a sharp pain in the middle of his lower back. The pain has not decreased, despite his taking naproxen around the clock. I look at the vital signs: temperature, 99°; pulse, 92 bpm; pressure, 140/90 mm Hg; respirations and oxygen saturation, normal. Nothing stands out as I click through the laboratory results.
