This occurs when one of the soft, gel-filled discs between the vertebrae of the spine bulges or ruptures, compressing and/or irritating the sciatic nerve. Another common cause of sciatica is muscle spasm that compresses the sciatic nerve as it travels through the muscles.
Other causes. Sciatica can be caused by tumours impinging on the spinal cord or the nerve roots. Severe back pain extending to the hips and feet, loss of bladder or bowel control, or muscle weakness, may result from spinal tumours. Trauma to the spine, such as from a car accident, may also lead to sciatica.
