Lower Back Pain or Neck Pain
Low back pain is not due to the pressure on a nerve root, as lower extremity pain is. Most low back pain is muscular or mechanical in nature, caused by overexertion, overuse, strain or sprain of the ligaments and tendons of the low back. It may also be attributed to degeneration of the disk space and facet joints, which hold the spine together. It may be caused additionally by arthritis or stenosis or referred symptoms
from organ involvement (bladder, gall bladder, kidney, prostate). One must also rule out organic causes as any form of cancer, especially prostrate CA.
Decompression relieves pressure that builds up on the discs and nerves. The task of relieving pain comes about as a result of drawing areas of herniated disc back into place.
Decompression achieves this by creating negative pressure within the disc, referred to as negative intra-discal pressure. This creates essentially a vacuum to draw the bulging and herniated disc material back into the disc space and relieve pressure.
Herniated discs are also often referred to as ruptured discs. A disc can bulge without herniating. When the jelly- like nucleus pulposis is under pressure, it can bulge. But, when the pressure is excessive, it can herniated (rupture) through the outer band called the annulus fibrosis. As the "herniated" disc material spills out, a portion can press on a nerve, causing pain and accompanying radiation and weakness of the muscles involved.
The nerve can get "pinched" resulting in the condition of sciatica, radiating pain to the buttocks and/or lower extremity (leg and calf). Over 90% of herniated discs occur in the lowest two levels of the lumbar spine, between L4/L5 and L5/S1.
This is the term used to reflect narrowing between the joints of the spine. The space in the spine joint is much smaller, or closed up. This narrowed condition, or closing up, causes "pinching" on the nerves within the spinal canal.
Spinal nerves supply movement, sensation and function of organs in the lower extremities. When these nerves are pinched within the canal, loss of function of the bowel, bladder and sexual activities as well as pain can be caused, radiating down to the lower extremities. The pain is generally worse when in a standing position or when walking due to the effects of gravity. When standing, there is more pressure on the nerves, but when bending over or sitting, the structures are opened, the ligament is stretched, resulting in decompression of the nerves
