Disc protrusions, bulging or herniated discs are all commonly referred to as a slipped disc. A slipped disc is a general descriptive term referring to degeneration or damage to the intervertebral discs. Spinal disc problems commonly lead to back pain with or without Sciatica.
Disks act as cushions between the vertebrae in your spine. They’re composed of an outer layer of tough cartilage that surrounds softer cartilage in the center. It may help to think of them as miniature jelly doughnuts, exactly the right size to fit between your vertebrae.
Disks show signs of wear and tear with age. Over time, disks dehydrate and their cartilage stiffens. These changes can cause the outer layer of the disk to bulge out fairly evenly all the way around its circumference — so it looks a little like a hamburger that’s too big for its bun.
