An issue with one of the rubbery cushions (discs) that lie in the spaces between the vertebrae that make up your spine is referred to as a herniated disc.
A spinal disc has a tougher, rubbery exterior covering a soft, jelly-like interior (nucleus) (annulus). A herniated disc, also known as a slipped disc or a ruptured disc, happens when a portion of the nucleus pushes through a tear in the annulus. Although a herniated disc can develop anywhere along the spine, it most frequently does so in the lower back. A herniated disc may cause pain, numbness, or weakness in an arm or leg, depending on where it is located. Many people with herniated discs don't experience any symptoms.
