Overview
Understanding sciatica
Sciatica is a symptom pattern rather than a single diagnosis. A herniated disc, spinal narrowing, or another condition can irritate a nerve root that contributes to the sciatic nerve.
Leg symptoms do not always come from the spine. Hip, vascular, peripheral nerve, and other problems can overlap, so the examination and history matter before treatment is discussed.
Useful context
What people may notice
- Burning, electric, aching, or sharp pain traveling down one leg
- Numbness or tingling in the buttock, leg, or foot
- Symptoms that change with sitting, standing, coughing, or spine movement
- Weakness in part of the leg or foot when a motor nerve is affected
At the clinic
How evaluation works
- 01
Map where symptoms begin and how far they travel.
- 02
Check strength, sensation, reflexes, movement, and gait when appropriate.
- 03
Review prior imaging and decide whether new imaging would change the plan.
- 04
Consider electrodiagnostic testing when the source or severity of nerve dysfunction remains unclear.
