Many of the pain sensing nerves of the spine are in the facet joints,
the two interlocking “fingers” at the back of each spinal bone. The normally smooth surfaces on which these joints glide, can become rough, irritated and inflamed. Surgical treatment often involves removing these facet joints, exposing the spinal cord.
Another cause of lower back pain can be a bulging disc putting pressure on the spinal cord or a nearby nerve
root. The result is often numbness, tingling or pain down the leg.
Cutting away the bulging disc tissue can permanently alter its ability to separate and cushion the adjacent bones. This rarely addresses the underlying structural cause of the problem.
