Your back pain can root for any of these causes

Disorders in the lower spine can cause sciatica pain. Sciatica is defined as mild to intense pain in the left or right leg. Sciatica pain cause arise by compression of one or more of the nerve networks spreading from the lower spine

Medical professionals at times call sciatica Radiculopathy, a medical term used to describe pain along with numbness, tingling and weakness in the arms or legs by pinching nerves. If the nerve root is pinched in the neck region, it is called the cervical radiculopathy. However, since the Sciatica affects the lower back it is called lumbar Radiculopathy

A set of nerve roots is combined in the lower spine to create the sciatica nerve. Beginning from the back of pelvis the sciatic nerve runs from the back, passing the buttock and downwards through the hip area into each leg. These nerve roots are not isolated network, but are a part of the body’s whole nervous system responsible for disseminating the signals of pain and sensation to the other parts of the body. Sciatica pain occurs when the nerve roots are pinched from a disc herniation or bone spurs. The conditions often occur prior to the sciatica pain and eventually interacts with the sciatica nerve

What Causes Sciatic Nerve Compression? 

Several spinal disorders can cause spinal nerve compression and leads sciatica pain causes. The  most common are:

  • A bulging or herniated disc
  • Lumbar Spinal Stenosis
  • Trauma
  • Spondylolisthesis

Bulging Disc or Herniated Disc

A bulging disc happens when the gel like center remains in the outer wall of the spinal disc. A herniated disc occurs when the nucleus breaks through the outer wall. Whether a disc bulges or herniates, disc material can press against an adjacent nerve root and compress delicate nerve tissue and cause sciatica.

Spinal Stenosis

Spinal stenosis is a nerve compression disorder most often affecting older adults. Leg pain similar to sciatica may occur as a result of lower Spinal Stenosis


Spondylolisthesis is a disorder that most often targets the lower spine. It is indicated by one vertebra slipping forward over an adjoining vertebra. When a vertebra slips and is dislocated, spinal nerve root compression occurs and often leads to sciatic leg pain.


Sciatica can result from direct nerve compression caused by sudden injuries or fall Examples includes motor vehicle accidents, falling down, football and other sports injuries. The effect may injure the nerves or, occasionally, fragments of broken bone may compress the nerves.
