Sciatic nerve is a network of nerves that branch out from the lower spine. When the Sciatic nerve is compressed at its source, pain is referred throughout the buttocks and can traverse down the leg reaching the toes. This makes Sciatica more difficult to diagnose as the referred leg pain often is mistaken for another injury such as a pulled muscle.
There are a number of causes of Sciatica and two of the most frequent are sitting and aging. Other causes are premature disc degeneration due to sports injuries. Playing football, running or even playing golf can cause the discs of the lower back to degenerate over the years, and the symptoms of Sciatica are felt long after you have stopped playing the sport. All of a sudden you are in pain merely from sitting and you don’t know the cause. Nine times out of ten the pain is from Sciatica.
