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:
- Aging.
- Excessive weight.
- Repetitive motions.
- Sudden strain from improper lifting or twisting.
What are the symptoms of a herniated disk?
Herniated disk symptoms vary depending on where the problem is in your spine. Symptoms worsen with movement and get better with rest.
