    Pathophysiology:
    Sciatica is generally caused by the compression of lumbar nerves or by compression of the sciatic nerve. When sciatica is caused by compression of a dorsal radix, it is considered a lumbar radiculopathy. When there is a tear in the anulus fibrosus, the nucleus pulposus may extrude through the tear and press against spinal nerves within the spinal cord, cauda equina, or exiting nerve roots, causing inflammation,
    numbness, or excruciating pain. Inflammation in the spinal canal can also spread to adjacent facet joints and cause lower back pain in the posterior thigh. Pseudosciatic pain can also be caused by compression of peripheral sections of the nerve, usually from soft tissue tension in the piriformis or related muscles.
