   Jan 31, 2024 · The sciatic nerve travels from the buttocks and down each leg. Sciatica most often happens when a herniated disk or an overgrowth of bone puts pressure on the lumbar spine nerve roots. This happens "upstream" from the sciatic nerve. This causes inflammation, pain and often some numbness in the affected leg.
