The sciatic nerve begins at the lower lumbar spine of the low back and runs through the buttock and down the back of the leg. Sciatica is characterised by compression or irritation of the sciatic nerve, which can cause low back pain and referred pain down one or both legs.
Sciatic nerve conditions can often present in many different ways, having a constant or intermittent nature. Usually there will be a component of sharp or “electric shock” type pain. Other commonly associated symptoms include burning, numbness, tingling, and muscle spasm or weakness.
Common aggravating factors include bending, lifting, sneezing, coughing, and extended sitting. It is often difficult to find positions of relief, but lying seems to be the most comfortable. Sciatica is usually experienced by labor-intensive workers, deskbound office workers and is common during pregnancy.
Causes of Sciatica
Sciatica is not a condition in itself; basically it’s an explanation of symptoms which can be caused by various injuries of the lower back and buttock. Acute episodes of sciatica could result from high impact trauma such as motor vehicle accidents or sporting injuries. It is also common for low impact activities such as bending, lifting or twisting to cause sciatic symptoms. Chronic episodes of Sciatica are generally due to degeneration of the Lumbar Spine as a result of long term misuse.
Pressure on the Sciatic nerve can result from a number of reasons including:
- Piriformis syndrome (tightness of the piriformis muscle in the buttock that compresses the sciatic nerve)
- Spinal misalignments, vertebral dysfunction
- Lumbar disc herniations or disc bulges
- Osteoarthritis and spinal degeneration
- Poor posture – wearing high heels, prolonged sitting, poor mattress
- Poor lifting technique and poor bending habits
- Spinal compressions due to osteoporosis
