Are disc bulges normal?
Often, yes.
84% of 80-year-olds with no back pain have one. So do 30% of 20-year-olds.
Are disc bulges normal with age?
Disc bulges show up on many scans of people who feel fine, and they show up more with age. A 2015 review of 33 studies, covering 3,110 people with no pain, found a disc bulge in 30% of 20-year-olds, 60% of 50-year-olds, and 84% of 80-year-olds (Brinjikji et al., AJNR).
If your MRI report says "disc bulge" or "degeneration" and you still hurt, that finding matters. It just may not be the whole story. This page is about what scans can and can't tell you.
Here are the figures for disc bulge from that review, by age:
| Age | People with no pain who had a disc bulge |
|---|---|
| 20 | 30% |
| 30 | 40% |
| 40 | 50% |
| 50 | 60% |
| 60 | 69% |
| 70 | 77% |
| 80 | 84% |
"Disc degeneration," another phrase you may see on a report, followed the same pattern: 37% at age 20, 68% at 40, 80% at 50, and 96% at 80.
The authors concluded that many of these findings are "likely part of normal aging and unassociated with pain," and that they "must be interpreted in the context of the patient's clinical condition." In plain words, your doctor's exam and your scan belong together.
Does everyone have disc bulges?
No. At age 50, about 4 in 10 of the people in the review didn't have one. But a bulge is ordinary enough that a scan can show one in someone who has never had pain there.
That's why the word on the report can feel scarier than it is. "Bulge" and "degeneration" sound like damage. On an MRI report, they often describe how a body looks at a certain age.
Why the scan and the pain don't always match
A scan shows structure. It can't show how sensitive your nervous system is.
Pain works partly like a protection system. After months of pain, stress, poor sleep, or worry about what the scan means, that system can turn its own volume up. Ordinary signals start to register as danger. The pain is real. Its level can depend on that alarm, as well as on what the picture shows.
That's one reason two people with the same scan can feel very different. It's also why a sensitized nervous system is worth raising with your doctor as one possible explanation, alongside what the scan shows.
Get checked first. See a doctor promptly if you have any of these, whatever your scan says:
- numbness in the groin or inner thighs
- weakness
- any change in bladder or bowel control
- fever
- weight loss you can't explain
- a history of cancer
- pain that started after a fall or accident
If a doctor has checked you and none of these apply, see how Relief works.
