For acute back pain lasting about three weeks with no red flags, what is the recommended initial approach?

• A. Clinical diagnosis only; no imaging or labs
• B. MRI to evaluate nerve compression
• C. CT scan to assess bone integrity
• D. Immediate surgical consult

Answer: (A)

The main idea being tested is how to manage acute low back pain when there are no red flags. In that situation, the best initial approach is to rely on history and physical examination to make a clinical diagnosis and avoid imaging or labs. Most uncomplicated acute low back pain improves with conservative care over a few weeks, so ordering tests doesn’t change outcomes and can expose patients to unnecessary costs, radiation (in imaging), and incidental findings that lead to more interventions. So, the recommended plan is to stay as active as tolerated, use simple analgesics like NSAIDs or acetaminophen as appropriate, and provide reassurance and education. Reserve imaging or laboratory tests for when red flags appear (such as fever, unexplained weight loss, history of cancer, severe weakness or numbness, saddle anesthesia or bladder dysfunction, major trauma, or symptoms persisting beyond about six weeks despite conservative care).
