When imaging or referral should be considered for suspected radiculopathy with persistent symptoms?

When imaging or referral should be considered for suspected radiculopathy with persistent symptoms?

• A. Symptoms lasting 1–2 days with sudden onset
• B. Dermatomal sensory/motor weakness with reflex changes and symptoms lasting beyond 4–6 weeks
• C. Pain only at rest with no neurological signs
• D. Improvement with standing

Answer: (B)

The key idea is that imaging or a referral is indicated when there are objective signs of nerve root involvement that persist over time. Dermatomal sensory and/or motor weakness with reflex changes point to nerve root irritation or compression, and when these symptoms last beyond 4–6 weeks, the likelihood of a structural issue increases and imaging helps identify the cause and guide next steps. Short-lived symptoms (1–2 days) without neurological signs aren’t enough to justify imaging, as many radicular problems resolve quickly. Pain only at rest with no neurological findings isn’t radiculopathy. Symptoms that improve with standing reduce concern for a significant nerve-root issue.
