A 25-year-old man presented to the ED with the chief complaint of low back pain. The pain onset gradually about 10 days prior, days after he lifted some furniture. The pain was described as dull and constant, with an intensity of level 7 out of 10 and getting worse in the past few days. He also had milder pain in the mid-back. Nothing seemed to make the pain better, and movement made the pain somewhat worse. He denied any prior back injury or surgery.
