Degenerative Disc Disease is a common cause of what is wrong with backs and necks. As a spinal disc degenerates the side walls first get drier and weaker and consequently begin to bulge taking up space and putting pressure on (or pinching) the spinal nerve root. In the early stages this bulge can come and go somewhat dependent upon what you did or didn't do yesterday explaining why your symptoms come and go. Second, as it gets drier and drier it gradually loses height and the vertebrae get closer together further compromising the space for the nerve and exaggerating the effect of the bulge. At this stage the symptoms tend to be more frequent and more severe. Third, the resulting stress on the joint causes a gradual calcium buildup much in the same way that stress on the skin of your hand results in a gradual buildup of skin. In the case of skin this buildup is called a callous and in the case of bone this buildup is called bone spurs or arthritis. The build up of bone further narrows the space for the nerve roots. At this stage the symptoms can be nearly constant. The effects of degeneration have culminated in a narrowing of the channel for the nerve root which is referred to as spinal stenosis.
Gravity Causes Stress On Your Spine
An inversion table counters the effect of gravity. When you hang upside down the weight of your upper body separates the vertebra temporarily increasing the space between them to possibly relieve enough pressure on the nerve to make it feel better. Temporarily. The trouble is that the disease remains, the disc is still degenerated.
There are many problems with inversion. Depending upon your body weight there may be way too much pressure being applied to the weakened disc fibers which runs the risk of tearing them further or there may not be enough force being applied to the right place at the right angle to actually result in any benefit. There is simply no way to measure the force or change the angle. Further, hanging upside down is at best uncomf
