Is Sciatica Causing Your Leg Pain?



( — Who would have ever thought that leg pain could be the symptom of a back issue? The body is a meticulous form, and what affects one system or attribute can become apparent in another.

Sciatica is commonly used to describe pain traveling in the distribution of the sciatic nerve. The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back. Branches of the sciatic nerve extend through the buttocks and down the back of each leg to the ankle and foot. Sciatica is a symptom caused by a disorder occurring in the lumbar spine. Here are the most common disorders that cause sciatica:


Sciatica can result from direct nerve compression caused by external forces to the lumbar or sacral spinal nerve roots. Examples include motor vehicle accidents, falling, and injuries sustained during football or other contact sports. The impact may injure the nerves or occasionally fragments of broken bone may compress the nerves.

Lumbar Bulging or Herniated Disc

A bulging disc is also known as a contained disc disorder. This means the gel-like center (nucleus pulposus) remains “contained” within the tire-like outer wall (annulus fibrosus) of the disc. A herniated disc occurs when the nucleus breaks through the annulus. It is called a “non-contained” disc disorder. Whether a disc bulges or herniates, disc material can press against an adjacent nerve root and compress delicate nerve tissue and cause sciatica. The consequences of a herniated disc are worse. Not only does the herniated nucleus cause direct compression of the nerve root against the interior of the bony spinal canal, but the disc material itself also contains an acidic, chemical irritant (hyaluronic acid) that causes nerve inflammation. In both cases, nerve compression and irritation cause inflammation and pain, often leading to extremity numbness, tingling, and muscle weakness.
