10 Causes of Sciatica
Reviewed: Dr. Gromatzky
Cause #1: Disc Herniation
Disc herniation is the most common cause of sciatica. It can affect anyone at any age. Normally, the intervertebral discs are constructed by cartilage (end plate), collagen fibers (annulus fibrosus) located on the outer side, and a softer part inside, which is otherwise known as nucleus pulposus.
In cases of a disc herniation, the soft part of the intervertebral disc will shift and protrude towards the edge of the disc. This can cause considerable damage and pain. Poor posture, a car accident, spine trauma, and a sudden increase in pressure through the disc can lead to disc herniation and sciatica.
