What Causes Sciatica? Understanding the Root of Nerve Pain

Sciatica is most commonly caused by irritation or compression of the sciatic nerve, which runs from the lower back down through the hips and legs. The most frequent reason this happens is a herniated or bulging disc in the lumbar spine. When a disc shifts out of its normal position, it can place pressure on nearby nerves, leading to symptoms such as sharp pain, tingling, numbness, or weakness that radiates down one side of the body.

Another major contributor to sciatica is spinal degeneration that develops over time. Conditions like arthritis, spinal stenosis (narrowing of the spinal canal), or chronic joint dysfunction can gradually reduce the space available for nerves to move freely. Poor posture, repetitive movements, or long periods of sitting—especially common in desk jobs and driving—can further stress the lower back and aggravate these underlying issues.

Lifestyle and biomechanical factors also play an important role. Muscle imbalances, weak core support, improper lifting mechanics, and previous injuries can all alter how the spine functions, placing uneven pressure on discs and joints. Over time, this mechanical stress can lead to inflammation around the sciatic nerve, triggering pain even without a major injury. Addressing these root causes early often helps prevent symptoms from becoming chronic or more severe.
