Three clues your leg pain is nerve related
Most leg pain isn't sciatica.
The term gets used so frequently that many people assume any pain radiating down the leg qualifies. But true nerve-related pain has specific clinical signatures that distinguish it from muscle strain, SI joint dysfunction, or referred pain from the lower back.
When we evaluate someone with leg pain, we look for three specific indicators.
→ Pain that tracks below the knee
If your pain stops at the thigh or knee, it's likely a different condition. True sciatic nerve involvement follows the anatomical path of the nerve down through the lower leg, often extending to the foot or toes.
→ Sensitivity to cough or sneeze
This finding surprises many patients.
Coughing or sneezing increases intrathecal pressure in the spinal canal. If this action triggers or intensifies your leg pain, it suggests nerve compression. This is a clinically significant finding that helps us differentiate nerve involvement from other sources of leg pain.
→ Changes in strength, reflex, or sensation
Can you perform a toe raise? A heel walk? Have you noticed numbness, tingling, or altered sensation in specific areas of your leg compared to the other side?
These neurological changes indicate the nerve is experiencing compression significant enough to affect its function, not just irritation.
When these three indicators cluster together, a focused neurological evaluation becomes important.
Accurate identification matters because different conditions require different approaches to care. The adjustment protocols we use for nerve compression differ from how we would address muscle strain or joint dysfunction.
Understanding these signs helps you recognize when professional evaluation is appropriate.
This self-assessment doesn't replace a clinical examination, but it provides helpful information about what may be occurring and whether earlier intervention could benefit your recovery.
