Pain originating from the intervertebral disc is described as discogenic pain. It occurs when the annulus fibrosus is cracked or fissured, the patient usually feels low back pain that may radiate along nerve root.
Herniated Nucleus Pulposus
This Is what is commonly called “waist Pain”. The intervertebral disc is like a cushion inbetween the vertebral bodies. The nucleus pulposus may bulge or pushes its way through a fissure in the annulus fibrosus. This may exert pressure on the nerve root causing pain.
This type of pain occurs when there is pressure on the nerve root by herniated disc. The pain is felt in the area supplied by the affected nerve root, that is why the patient describes it as spreading from the back down to his leg.
