What it is
The spinal canal and the openings where nerves exit (foramina) can narrow over time from disc bulges, thickened ligaments, or bony changes. Reports grade it as mild, moderate, or severe.
How common is it?
Very common in adults over 50. Many people with mild or even moderate stenosis on imaging have no symptoms at all.
What's usually next
Treatment is guided by symptoms, not the picture alone — usually starting with physical therapy, activity changes, and pain management. Severe, symptomatic stenosis has more options, including injections or surgery.
When it usually isn't — and when it might be — worrying
Usually reassuring
- Described as “mild” without nerve compression
- No leg or arm symptoms
- Findings called “age-appropriate”
Worth discussing with your doctor
- Described as “severe” or “critical” narrowing
- Leg weakness, numbness, or trouble walking
- Loss of bladder or bowel control (seek urgent care)
Questions to ask your doctor
- 1How severe is the narrowing, and at which levels?
- 2Does it match my symptoms?
- 3What non-surgical options should I try first?
- 4What warning signs mean I should be seen urgently?
