Sciatica refers to any pain or compression of the sciatic nerve.  The sciatic nerve runs from the back of the pelvis and right down through the buttocks and both legs and ends at the feet. If something presses on the sciatic nerve it can cause a pain that runs from the lower back and down the leg; this pain can be mild to severe.

Sciatica

Causes of sciatica include slipped discs which can get temporarily moved out of place and then press on the sciatic nerve.  Acute sciatica is pain which lasts up to six weeks whereas chronic sciatica lasts longer than six weeks. Most cases clear up unaided but using painkillers, hot or cold compresses and exercise can help to alleviate symptoms. Sometimes there is a need to contact a physiotherapist especially for chronic sufferers.

Sciatic pain is different to back pain in that it also affects the legs.  Sciatica can cause weakness in the legs or feet. There is a rare condition which can cause sciatica and this is called Cauda Equine Syndrome.  This can lead to paralysis if left untreated as it can permanently damage the nervous system.  A sign of cauda equine syndrome is the sudden loss of bladder or bowel control and if this occurs immediate medical help should be sought.

Another cause of sciatica has been put down to general wear and tear.  This is why people over forty with jobs involving a physical activity are more prone to sciatica.
