A disc is a cartilage component that separates 2 vertabrae. By separating these two structures, it allows a space for 2 spinal nerves to exit, one on each side. A spinal nerve is a nerve that comes directly from the spinal cord. Spinal nerves are always in pairs. They extend from the cord and exit bilaterally through the neural foramen, or "spinal nerve holes." When a disc bulges, it decreases in height. By doing this, the size of the foramen are decreased. The foramen are determined by the disc height. As a disc degenerates, the foramen becomes more and more narrowed. The spinal nerves can be put in great danger if the disc continues to degenerate. A chiropractor is the answer to this problem. Surgery should be a last resort. It's like a hard boiled egg. It can't be unboiled.
