What vertebrae causes sciatica?
The origins of sciatic pain can begin as high as the L4 (lumbar) vertebrae and as low as S1 (sacrum) vertebrae. Each vertebra—including L5—has a corresponding nerve root that feeds to the sciatic nerve; depending on which root is affected, symptoms may vary slightly in where they radiate to.
