What is a herniated disc?
A herniated disc (also called bulged or ruptured) is a fragment of the disc nucleus that is pushed out of the annulus, into the spinal canal through a tear or rupture in the annulus. A herniated disk is also known as a slipped, ruptured, or bulging disk. It’s one of the most common causes of neck, back, and leg pain
What causes a herniated disk?
Disks have soft, gel-like centers and a firmer outer layer, like a jelly doughnut. With time, the outer layer weakens and can crack. A herniated disk happens when the inner “jelly” substance pushes through the crack. The leaked material may press on nearby spinal nerves.
Several factors can contribute to a disk rupture, including:
- Repetitive motions
- Sudden strain from improper lifting or twisting
