Sciatica pain can cause severe and debilitating pain along with tingling, burning, numbness and weakness of the legs. Sciatica usually occurs when the sciatica nerve is irritated or compressed by a problem in the lower back sending pain down the buttock, hamstring, calf and foot.
This is a serious health issue. It is estimated that 40% of the population will experience some degree of sciatica pain in their lifetime. Sciatica pain can vary and encompasses mild cramping, a tightening sensation in the hamstring or calf muscles to an all out constant shooting pain from the buttock down to the foot.
The sciatic nerve runs from the lower part of the spine down the back of both legs forming what can be though of as an electrical cable to and from the brain.
