Sciatica - neuralgia of the sciatic nerve


Sciatica - neuralgia of the sciatic nerve

Sciatica (neuralgia of the sciatic nerve) - a condition in which the notes back pain, radiating to the lower limb. Usually the pain goes behind the knee and can be up to the foot. Sometimes there may be other than pain muscle weakness.


Sciatica - pain is associated with damage or irritation of the sciatic nerve - the largest nerve in the body. This nerve is formed by merging the last two lumbar nerve roots and the first three sacral nerve roots. The sciatic nerve provides both motor and sensory branches to the lower extremity.

Sciatica is different from other forms of back pain that a person has two sciatic nerve, and pain is usually observed in only one of them.

Pain sciatica usually "shooting" character, like an electric shock. In addition, there may be a burning sensation in the foot or "tingling chills." The degree of pain can be mild to intense. Some patients may experience pain in one leg, with tingling and numbness in another part of the same leg.

Neuralgia of the sciatic nerve irritation caused by it in any factor. In most cases, you can not even remember what led to the emergence of these pains. Sometimes the pain can occur after a sharp rise of gravity or awkward movements.

Herniated disk

The sciatic nerve can injure or stretch. Herniated Disc - is the most common cause of sciatica.

Intervertebral disk - it is like a "seal", which absorbs movement and pressure on the vertebrae. If herniated disc protrusion noted his inner nucleus pulposus through the destroyed annulus disc. This leads to compression of nerve root or the denial that comes out of the intervertebral foramen. By the sciatic nerve causes a herniated disc in the lumbar spine.

Stenosis of the lumbar spinal canal

This condition is associated with narrowing of the lumen of the canal, which houses the spinal cord and from which nerve roots emerge. Usually this condition occurs mainly in people older than 60 years and is the result of increased vertebral facet joints, excessive formation of soft tissue and prominence of the intervertebral disc pressure on the nerve roots that extend from the spinal cord and pass through the intervertebral foramen. As a result of this nerve is compressed, prejudiced, and there is pain and other symptoms of neuralgia of the sciatic nerve.

Osteochondrosis

Osteochondrosis - a degenerative disease of the spine, which marked changes in the intervertebral discs of "flattening", and the protrusion of bone accretion build-up. These bone growths can compress or irritate the nerve roots.

Spondylolisthesis

Spondylolisthesis - a condition in which the observed slippage of one vertebra over another. As a result, may also be infringing or compression of nerve roots that form the sciatic nerve (for example, if the 5th lumbar vertebra slips from the 1st sacral).

Piriformis syndrome

In this syndrome, there may be irritation or stretching of the sciatic nerve piriformis muscle. This nerve passes just under the piriformis muscle, right behind her. This syndrome does not apply to the sciatic nerve, but the pain in his leg when it is the same as in sciatica.

Violation of the functions of the sacroiliac joint

In the area of the junction of two bones is the 5th lumbar nerve root. During stimulation of the joint can be observed taking place here and irritation of the nerve, which also causes pain.

Other rare but very serious causes include: swelling, blood clot, an abscess, as well as Lyme disease, fibromyalgia, infections in the pelvic cavity, Reiter's syndrome.
