What Causes Sciatica Nerve Pain?

Sciatica pain is often confused with other sorts of back ache. Sciatica pain is resulting from and felt along the path of the large sciatic nerve, which travels from the bottom of the spine and down each buttock, leg, and foot. If you feel radiating pain along this course, you might be experiencing sciatica pain.

Some common causes of sciatica nerve compression

Several spinal problems can become sciatica pain causes, the most common or usual reasons are;

  • Spondylolisthesis
  • Trauma
  • Bulging or herniated disc
  • Piriformis syndrome
  • Spinal tumor
  • Lumbar spinal stenosis


Spondylolisthesis is a disease that most often affects the lumbar spine. It is characterized by one vertebra slipping ahead over an adjoining vertebra. When a vertebra slips and is displaced, spinal nerve root compression occurs and regularly causes sciatic leg pain. Spondylolisthesis is considered as developmental (discovered at birth, develops at some stage in childhood) or acquired from spinal degeneration, trauma or physical stress such as weight lifting, gymnastics.


One of the sciatica pain causes is direct nerve compression as a result of external forces to the lumbar or sacral spinal nerve roots. Examples encompass motor car accidents, falling down, football and other sports. The impact might also injure the nerves or, occasionally, fragments of damaged bone may also compress the nerves.

Herniated disc

A herniated disc happens when the nucleus breaks by means of the annulus fibrosus. It is referred to as a non-contained disc disorder. Whether a disc bulges or herniates, disc material can press against an adjoining nerve root and compress delicate nerve tissue and reason sciatica.

Not only does the herniated disc reason direct compression of the nerve root against the interior of the bony spinal canal, but the disc material itself also includes an acidic, chemical irritant that reasons nerve inflammation.

Piriformis syndrome

Piriformis syndrome is that sciatica pain causes which is named for the piriformis muscle and the pain brought about when the muscle irritates the sciatic nerve. The piriformis muscle is found within the lower portion of the spine, interfaces to the thighbone, and helps in hip rotation. The sciatic nerve goes below the piriformis muscle. Piriformis syndrome develops when muscle spasms develop within the piriformis muscle thereby compressing the sciatic nerve.

Spinal tumor

Spinal tumors are odd growths which can be either benign or cancerous. Fortunately, this sciatica pain causes is rare. However, when a spinal tumor develops inside the lumbar region, there is a chance for sciatica to develop due to nerve compression.

Lumbar spinal stenosis

Spinal stenosis is a nerve compression disorder most frequently affecting older adults. Leg pain much like sciatica may occur as a result of lumbar spinal stenosis. The back pain is commonly positional, regularly brought on through activities inclusive of standing or walking and relieved through sitting down. When spinal stenosis develops, the spinal cord passageways emerge as narrow or clogged causing nerve compression.
