2. Spinal Stenosis

Spinal stenosis is a narrowing in the spinal canal, which the bones in the spine form to protect the spinal cord. When this area narrows, it compresses the sciatic nerve, resulting in sciatica. Causes of spinal stenosis include an overgrowth of bone due to damage from osteoarthritis, thickened ligaments that bulge into the spinal canal, and spinal injuries that lead to dislocation or fracture of the bone, which then narrows the space.
