Discogenic pain is thought to occur in relationship to disc degeneration. It’s theorized that this pain occurs when nerve receptors located in the outer part of the annulus are irritated by inflammation or other conditions. For example, if the inflammatory chemicals from an annular tear reach the nerves in the outer part of the annulus, the tear may be the cause of discogenic pain.
Genetics can also influence the chemical composition of discs, which can lead to discs drying out faster than normal and becoming less capable of evenly bearing the spinal load. Damage to the edge of the vertebra adjacent to the disc may also occur.
Symptoms of Discogenic Pain
The main symptom of discogenic pain is an aching pain localized in your back. Unlike many kinds of back pain, discogenic back pain doesn’t refer to your leg or arm and does not impact your ability to use your limbs.
Discogenic low back pain usually worsens when your spine is compressed through activities like sitting, bending, or coughing. This type of pain typically subsides when you lie down, relieving the compression. Discogenic neck pain is worse you turn or tilt your head, or when you hold your head in one position too long. Muscle spasms sometimes accompany discogenic neck pain.
