Sciatica Nerve Pain Explained

Sciatica refers to the pain that radiates along the sciatic nerve, which branches off from the lower back and travels through the hip and buttocks and down each leg. Sciatica (pronounced as sigh-at-eh-kah) is not actually a medical diagnosis or a disease, it is a symptom of an underlying condition. It describes the symptoms of pain in the leg, including numbness, tingling or weakness, usually at the back of the leg where the sciatic nerve is present.

A pinched nerve, on the other hand, may result in sciatic pain. As the name suggests, a pinched nerve is a nerve that has been compressed or ‘pinched’ at some point along its path. The location of the compressed part of the nerve will determine what kind of symptoms result.

Anatomy of the Sciatic Nerve

This is the largest nerve in our body. It carries various nerve roots, which start at the spine and branch out in the lower back. They then combine to form the sciatic nerve. This large nerve begins at the level of L3 (or lumbar segment 3) of the spine in the back. The nerve then runs from the lower back, through the buttock and travels down the back of each leg. Various nerve fibers branch out into the leg, innervating the thigh, calf, foot, and toes along the way.

Causes of Sciatic Pain

As we already know, sciatica pain is usually caused by an underlying medical condition. Some of the common causes of conditions resulting in sciatic nerve pain are as follows:

  • Lumbar herniated disc (bulging of the vertebral disc due to rupture)
  • Bone spur (bony projection)
  • Degenerative disc disease (the breakdown of discs which act as cushions between the vertebrae and support them)
  • Spinal Stenosis in the lumbar region (narrowing of the spinal canal in the lower back)
  • Spondylolisthesis (one vertebra slips forward over another one)
  • Pregnancy
  • Muscle spasm in the back or buttocks
  • Infections affecting the spine

Some other things that can worsen the back pain include being obese or overweight, lack of regular exercise, wearing high heels, sleeping on a mattress that is either too soft or too hard.

Symptoms of Sciatic Nerve Pain or Sciatica

  • The main feature of sciatica is a constant pain in the leg, usually on one side. Pain in both the legs rarely occurs.
  • The pain extends from the buttock down the leg and goes down till the foot and toes.
  • The pain is very sharp, burning or piercing.
  • Pain is worse on sitting or may make it difficult to stand up or walk.
  • Weakness, tingling or numbness on moving the leg, foot or toes.

The pain may be severe and constant, or not very frequent and just somewhat irritating. This depends on the location where the nerve is pinched. Most of these symptoms occur when the Sciatic nerve is compressed or pinched near its point of origin.

Sciatic pain rarely develops in young people. It occurs more commonly around the age of 40-50 years. As this term is generally used to refer to any pain in the leg and back, its prevalence varies widely. This tends to develop over time rather than being caused by an injury or a trauma.
