Sciatica Causes - WelcomeCure

Spinal Disc Herniation: Approximately 90% cases of Sciatica occur as a result of a herniated spinal disc compressing on the nerve root in the spine.
Stenosis: Narrowing of the lumbar canal or intervertebral formina exerts pressure on the sciatic nerve giving way to Sciatica.
Piriformis Syndrome: Piriformis is one of the muscles present in the region of the buttocks. If this muscle gets shortened due to trauma or overuse, it can impinge on the sciatic nerve bringing on pain.
Pregnancy: This is one of the causes of Sciatica of the temporary type. The sheer weight of the growing foetus can compress the nerve, especially during the act of sitting. It recovers automatically after delivery.
Tumours and cysts along the line of the sciatic nerve are other possible causes of Sciatica.
Spondylolisthesis: This is a condition where one vertebra slips forward over another one, causing compression of the nerve roots present within their canals. Spondylolisthesis occurs as a result of a direct injury or accidents.
