A herniated disk refers to a problem with one of the rubbery cushions (disks) that sit between the individual bones (vertebrae) that stack to make your spine.

A spinal disk has a soft, jellylike center (nucleus) encased in a tougher, rubbery exterior (annulus). Sometimes called a slipped disk or a ruptured disk, a herniated disk occurs when some of the nucleus pushes out through a tear in the annulus.

A herniated disk, which can occur in any part of the spine, can irritate a nearby nerve. Depending on where the herniated disk is, it can result in pain, numbness or weakness in an arm or leg. Most herniated disks occur in the lower back, although they can also occur in the neck. Signs and symptoms depend on where the disk is situated and whether the disk is pressing on a nerve. Disk herniation is most often the result of a gradual, aging-related wear and tear called disk degeneration.

puts pressure on the spinal cord or a single nerve fibre. This means that not only will a slipped disc cause pain in the area of the disc, but also in regions that the nerve controls, such as an arm or a leg.
