Sciatica is pain that starts in the back and radiates down one of the legs. It is quite a common complaint. sciatica is caused by pressure on the sciatic nerve which runs down into the leg. The cause of pressure can be varied from a Slipped (Prolapsed) disk to muscle tension (Piriformis syndrome) or something less common such as a tumours, bony growths and infections.

  1. The most common symptom of true sciatica is posterior thigh, lower leg or foot pain that can be much worse than the accompanying lower back pain.
  2. Usually a patient will experience moderate to severe pain, which begins in the buttocks and runs down through the leg or foot.
  3. Often a patient will have a previous history of lower back pain beginning a few days or weeks before the leg pain occurs, then the leg pain becomes worse than the back pain, and in some cases the back pain will completely disappear.
