What is Sciatica?
The sciatic nerve in the spine runs from the lower back through the hips and buttocks, and down each leg. Pain associated with this nerve is called sciatica. Sciatica pain radiates through the sciatic region, and usually affects only one side of the body.
Causes of Sciatica
Most cases of sciatica are caused when a bone spur, herniated disc, or muscle spasm, compresses part of the nerve. Other causes of sciatica include:
- A tumor compressing the sciatic nerve
- Lumbar spinal stenosis
- Spondylolisthesis (a condition in which one vertebra slips forward and partially covers another vertebra)
- Pregnancy-induced pressure on the sciatic nerve
Being overweight, having a sedentary lifestyle, wearing high heels, or sleeping on a mattress that’s too hard or too soft can make sciatic pain worse.
