What is Sciatica?

Sciatica is the set of symptoms that is produced by compression or irritation of the sciatic nerve, which originates in the lower back and is the longest nerve in the body. These symptoms can include focal pain, radiating pain, tingling, numbness, a warm or hot sensation, and/or weakness in the muscle group innervated by the compressed nerve. Areas of the body that can be affected by sciatica include the lower back, the buttocks, the thighs, the lower legs, and the feet. Symptoms usually are experienced only on one side of the body, which is determined by the side of the spinal canal where nerve compression is present.

Conditions that Cause Sciatica

Lower back pain affects millions of people every year. It is among the most common reasons cited for missed work among people middle aged and older. The underlying causes of sciatica often are related to the aging process. These degenerative spine conditions can be exacerbated by lifestyle extremes - meaning the person suffering from them is either far too sedentary, or active to the point of overexertion. In general, age-related deterioration of the components of the lumbar (lower back) anatomy is responsible for conditions that can lead to sciatica, including:

Treatment for Sciatica

Sciatic nerve compression symptoms usually can be managed with a regimen of conservative treatments, including non-steroidal anti-inflammatory drugs (NSAIDs), physician-approved exercise and stretching, and other methods. In some cases, corticosteroid injections may be necessary to temporarily reduce inflammation around the nerve. Sciatica surgery generally is a last resort, reserved for those who are unable to find relief after several weeks or months of conservative treatment. Anyone considering surgery for lower back pain should discuss risks and potential side effects with a trusted physician before consenting to undergo any procedure.
