The Top Causes Of Sciatica Revealed
March 19, 2026
Bottom Line
Here's something that might surprise you: sciatica can be caused by a number of different conditions. It's not always a herniated disc!
The Top Causes
Herniated Discs
When the soft gel-like center of a spinal disc pushes through a tear in the tough outer layer, it can press against the sciatic nerve root, causing pain, numbness, and weakness.
Spinal Stenosis
A narrowing of the spaces within your spine can put pressure on the nerves that travel through the spine, including the sciatic nerve. This condition is most commonly caused by age-related wear and tear.
Degenerative Disc Disease
The natural breakdown of spinal discs over time. As discs lose hydration and height, they can bulge or herniate more easily.
Spondylolisthesis
When one vertebra slips forward over the one below it, narrowing the space through which the nerve exits the spine.
Piriformis Syndrome
When the piriformis muscle, located deep in the buttock, spasms and irritates the sciatic nerve.
