Sciatica is a spine condition where pain travels and radiates along the sciatic nerve, the largest nerve of the spine. The pain usually occurs on one side of the body only, beginning from the lumbar region, covering the hips and buttocks, then going down on either one of the legs.
Sciatica is a form of pinched nerve or related somehow since the nerve causing the pain is compressed and is disrupted by its normal function.
Sciatica is triggered when there is irritation on the nerve roots in the lumbar and sacral region. Sciatica could be the effect of other spinal conditions, such as herniated/bulging discs, spinal stenosis or narrowing of the spinal column, and degenerative disc disease.
