As has been previously reported, lumbar disc herniation, or sciatica, is one of the most common spinal conditions confronting the general population. At some point in time, most people between the ages of 30 and 70 will experience a sciatica, in which the lumbar shock absorber, the disc, protrudes or bulges out to pinch on a nerve. This usually happens after some degree of twist, turn, or light trauma, but very often without any particular triggering event. Most of these herniations lead to a central or slightly lateral disc herniation, which will affect either one leg or the other, depending on whether it is right- or left-sided.
