Most common causes of Sciatica
Sciatica is caused by irritation of the root(s) of the lower lumbar and lumbosacral spine.
Additional common causes of sciatica include:
Disc Herniation - where a disc bulges and causes compression or irritation to a nerve/nerve root - The lumbar region of your spine, commonly referred to as the lower back, is comprised of five vertebrae, and in between each vertebra are spinal discs. These discs cushion the joints of your spine and provide much-needed support.
Degenerative disc disease (breakdown of discs, which act as cushions between the vertebrae)
Piriformis syndrome - Piriformis syndrome is a condition in which the piriformis muscle, located in the buttock region, spasms and causes buttock pain. The piriformis muscle can also irritate the nearby sciatic nerve and cause pain, numbness and tingling along the back of the leg and into the foot (similar to sciatic pain).
Lumbar spinal stenosis - Spinal stenosis occurs when the space around the spinal cord narrows. This puts pressure on the spinal cord and the spinal nerve roots, and may cause pain, numbness, or weakness in the legs
Spondylolisthesis - a condition in which one vertebra slips forward over an adjacent segment.
