The sciatica is characterized by a pain that begins in the lower back and goes down into one or both legs. This pain could vary in intensity and frequency; minimal, moderate, severe and occasional, intermittent, frequent or constant. The sciatica pain feels like a electric shocks or like a pins or needle and even toothache-like. Other symptoms associated with sciatica include burning, numbness and tingling sensations. All this discomforts are caused by the compression of the sciatic nerve as the result of the lumbar spine subluxations (misaligned vertebrae), herniated or bulging discs (slipped discs), or other conditions like pregnancy and childbirth, tumors, and non-spinal disorders such as diabetes.
