Which of the following best describes the effect of coughing or sneezing on radicular pain due to disc herniation?

• A. Worsens radicular leg pain
• B. Improves radicular leg pain
• C. Has no effect
• D. Only affects the back, not leg

Answer: (C)

Radicular pain from a herniated disc is driven mainly by irritation and compression of the affected nerve root, which is a relatively static mechanical issue during a brief coughing or sneezing event. The brief rise in intrathecal and epidural pressure that occurs with a cough or sneeze does not reliably change how the nerve root is pressed or irritated, so the distribution and intensity of the radicular pain tend to remain the same. In other words, this transient pressure change doesn’t consistently worsen or relieve the leg pain, making the overall effect on radicular symptoms minimal. (Note: other pain generators, like facet joint pain, can respond differently to such maneuvers, but for a typical disc-related radiculopathy, there isn’t a significant change.)
