WHAT IS A HERNIATED DISC?
Your spine has 23 intervertebral discs between its vertebrae that act as shock absorbers. Each disc has a thick, fibrous outer layer and a gel-like centre. When a disc gets too much pressure on one side, the gel pushes toward and can rupture the opposite side of the outer layer. That’s a herniated disc. It’s most prevalent in men ages 30 to 50, and almost always in the lumbar (lower) spine. It’s certainly not the only cause of back pain, but it’s one of the most severe and surprisingly common. Painful on its own, an unlucky herniated disc can also press on nearby nerves for an extra layer of hurt.
