What is the typical clinical presentation of lumbar disc herniation with radiculopathy?

• A. Bilateral leg pain without dermatomal pattern and no radicular signs.
• B. Ipsilateral leg pain radiating in a dermatomal pattern, possibly worsened by coughing or sneezing, with positive straight leg raise and possible mild weakness and diminished reflexes.
• C. Pure low back pain without leg symptoms.
• D. Acute thoracic pain with rib tenderness.

Answer: (B)

The main idea is that lumbar disc herniation with radiculopathy typically causes pain that travels down the leg on the same side as the herniation, following a specific nerve root dermatomal pattern. This means the leg pain is not just general leg ache but follows the map of a nerve root (often L5 or S1), and it’s usually accompanied by signs of nerve irritation such as a positive straight leg raise test. You may also see mild weakness in muscles supplied by the affected root and reduced reflexes, reflecting partial nerve compression rather than a complete motor loss. The pain is often worse with activities that increase spinal pressure, like coughing or sneezing, because these maneuvers intensify nerve root irritation. If the presentation is just back pain without leg radiation or dermatomal pattern, that would be less consistent with radiculopathy. Thoracic pain with rib tenderness points to a different region altogether than a lumbar disc herniation.
