Sciatica


Sciatica is a set of symptoms including pain that may be caused by general compression or irritation of one of five spinal nerve roots that give rise to each sciatic nerve, or by compression or irritation of the left or right or both sciatic nerves.

Symptoms include lower back pain, buttock pain, and pain, numbness or weakness in various parts of the leg and foot. Other symptoms include pins and needles or tingling and difficulty in moving or controlling the leg. Typically, the symptoms are only felt on one side of the body. The pain may radiate below the knee, but does not always.

Although sciatica is a relatively common form of low back and leg pain, the true meaning of the term is often misunderstood. Sciatica is a set of symptoms rather than a diagnosis for what is irritating the root of the nerve, causing the pain. The treatment for sciatica or sciatic symptoms often differs, depending upon the underlying cause and pain levels. Causes include compression of the sciatic nerve roots caused by a herniated (torn) or protruding disc in the lower back.

Evidence suggests that spinal manipulation is an effective treatment for acute sciatica. Spinal manipulation has been found to be generally safe and beneficial for the treatment of disc-related pain.
