What an MRI actually tells you about sciatica
You are in pain, so you get sent for a scan. Reasonable. Here is what nobody explains before you go
in: an MRI is very good at showing structure and very bad at showing cause. It photographs your spine
at rest, lying still, in the one position where your pain is usually quietest.
What to expect from the scan itself is simple — 20 to 45 minutes, loud, no needles, no radiation,
and you can ask for the open machine if tight spaces bother you. What to expect from the
report is the part that gets people in trouble.
Findings are common. Pain is specific.
Disc bulges, degeneration and “changes consistent with age” show up on scans of people who feel
perfectly fine. Meanwhile plenty of people in genuine agony get a clean report and are told there is
nothing wrong with them. Both groups are being failed by the same mistake: treating the picture as the
problem.
In 34+ years I have watched imaging send people straight to the most invasive option on the menu
when the actual driver was an imbalance — one side of the body quietly quitting, the other side
covering for it for years.
What to do with your results
- Read the whole report, not the scary noun. “Bulge” is not a sentence to surgery.
- Match the finding to your symptoms. If the report says left and your pain is
right, that finding is not your story. - Test movement before you consent to anything. If working the non-painful side
changes your pain in days, no scan was ever going to find that.
Real red flags — loss of bowel or bladder control, saddle numbness, progressive weakness, a foot
you cannot lift — belong in a doctor’s office today. Everything else is usually worth trying the
non-invasive route first.
