A slipped disc, or herniated disc, is a condition where one of the rubbery cushions (discs) between your vertebrae develops a tear in its outer layer, allowing the gel-like centre to protrude. This protrusion can compress nearby nerves, causing pain, numbness, or weakness in the affected area.
Despite its name, the disc doesn’t actually “slip” out of place. Instead, the disc’s inner material herniates through a weakened area in the outer ring. This condition most commonly affects the lower back (lumbar spine) but can also occur in the neck (cervical spine).
