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.
- 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.
- Usually a patient will experience moderate to severe pain, which begins in the buttocks and runs down through the leg or foot.
- 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.
