Discogenic Low Back Pain is a collection of sudden, sharp pain sensations arising from the fibrous part of your intervertebral discs. The vertebral joints are supported by cartilaginous discs made up of a tough fibrous covering called the annulus fibrosus enclosing a jelly-like substance known as the nucleus pulposus.
There are pain-sensitive nerve endings within the annulus fibrosus, and chemical or physical changes can bring about Discogenic Low Back Pain. Please note that this is contrary to disc herniation pain which there is a rupture of this capsule, causing the nucleus pulposus to push out and put pressure on the nearby spinal nerves, causing pain. Discogenic Low Back Pain is caused by the stimulation of nociceptors within the annulus fibrosus.
