The sciatic nerve, the largest in the body, controls muscles in the back of your knee and lower leg and also provides sensation to the back of the thigh, lower leg and sole of the foot.

A problem with this nerve is called sciatica and may lead to pain, numbness, weakness or tingling from the lower back on down. Sciatica usually affects one side of the body. Causes may be a ruptured disc, narrowing of the spinal canal (spinal stenosis) or an injury.

 Sciatica is most commonly a result of a lumbar disc herniation directly pressing on the nerve. However, any cause of irritation or inflammation around the sciatic nerve can cause symptoms of sciatica. This irritation of nerves as a result of an abnormal intervertebral disc is referred to as radiculopathy. Aside from a disc pinched nerve, other causes of sciatica include nerve irritation from adjacent bone, tumors, muscle, internal bleeding, infections in or around the lumbar spine, spondylolisthesis, injury, spinal stenosis, cauda equina syndrome, osteophyte, and others. Sciatica can sometimes occur due to irritation of the sciatic nerve during pregnancy. Contact NMA for a thorough evaluation and treatment options that best fit your needs.

Ruptured or Herniated Disc and Sciatica

If the spinal column tears open and the discs protrude outward, they can press on, or “pinch,” nearby spinal nerves. This is known as a ruptured, herniated, or slipped disc. A ruptured disc causes severe low back pain and, sometimes, shooting pain down the back of the legs, which is known as sciatica.
