Sciatica Or Piriformis Syndrome – Which Is It?
A large amount of confusion and misunderstanding exists concerning the conditions sciatica and piriformis syndrome. There are some who insist that the two conditions are actually the same thing, but even though they can have symptoms that are very much alike, the underlying causes differ. Sciatica refers to irritation of the sciatic (often mis-spelled as syatic or psyatic) nerve, that arises from nerve roots in the lumbar spine. The most common cause of sciatic nerve irritation, or “true” sciatica is compression of one or more of its component nerve roots due to disc herniation or spinal degeneration in the lower lumbar region. Sciatica usually begins in the buttock area and, depending on the severity of the underlying nerve comression and inflammation, may extend down the entire leg to the ankle and foot.
