Disc degeneration
In plain language
Age- and use-related changes in a spinal disc; the image alone does not explain every episode of back or neck pain.

3 things to know first
- It describes a disc changing over time. It is not automatically a dangerous disease.
- Many people have no symptoms. Imaging changes and pain often differ.
- It is narrower than spondylosis. Spondylosis may include joints and bone as well as discs.
What it is
Spinal discs sit between vertebrae and help distribute load. With time, a disc may lose water content, change shape, or become lower in height. The term degeneration describes those changes rather than one specific cause of pain.
Why it appears on your report
MRI can show altered disc signal and shape; X-ray or CT may show reduced disc height or nearby bone changes. The report usually names the level and any associated bulge, herniation, or nerve narrowing.
How serious is it
Common degenerative changes may be incidental. Their importance depends on symptoms, neurological findings, and whether a disc affects nearby nerves.
When to seek care urgently
Seek urgent help for progressive weakness, saddle numbness, or new bladder or bowel control problems.
What usually happens next
- Match symptoms to the involved level.
- Review any nerve compression or other findings.
- Plan symptom management and follow-up with a clinician.
