The sciatic nerve has the distinction of being the largest and longest nerve in the body and when irritated, causes pain that elicits the familiar phrase, "oh, my aching back!" The sciatic nerve is as wide as your thumb and runs from the lower back, down the buttocks, legs and to the feet. It's responsible for the painful condition referred to as sciatica. When this nerve is compressed or strained, the resulting irritation can play havoc with everyday life. For example: * It's responsible for more lost days of work, other than the common cold. * Treating it can run into billions of healthcare dollars. * It can interfere with being able to carry out the simplest everyday duties without pain
