Slipped Disc (Herniation)
Movement in the discs that reside between the spinal vertebrae are by far the most common reason for cases of sciatica. These discs are made up of a spongiform ring of cartilage, inside which lies a gel-like centre. They are there to help cushion the spine from compressive forces that would otherwise result in serious pain and injury.
However, rotational movements, heavy lifting and prolonged sitting are just some of the ways these discs can become damaged, leading to conditions such as sciatica.
Herniation of the disc is slightly different, but is equally a cause of spinal pain. Herniation of the disc occurs when the centre of the disc extrudes into the spinal canal, compressing the nerve and leading to tension and pressure which can result in quite severe aches and pains.
