Chronic Lower Back Pain After Auto Injury: What Actually Changes
Dr. Rachel Medford
Doctor of Chiropractic at Medford Chiropractic
A recurring case pattern at Medford Chiropractic looks like this: a patient was in a car accident years ago, went to the hospital, did a course of physical therapy, and still lives with lower back pain that never fully went away. In some cases there is a documented disc injury — a compressed segment between L4 and L5 is common — and the working assumption has been that they just have to live with it.
They usually do not.
Why the pain outlasts the injury
Acute soft-tissue and disc injuries heal on their own timeline. What often stays behind is a compensation pattern: the segments above and below the injured area moved differently to protect it, the pelvis started tilting to unload it, and over time the nervous system locked in that pattern as "normal." Physical therapy strengthens muscles, but if the joints those muscles cross are still moving in a compromised pattern, the pain keeps coming back.
What we address first
We start with the joints that stopped moving well after the injury — usually the segments just above and below the primary injury site, and the sacroiliac joints. Restoring motion there takes pressure off the disc, allows the surrounding muscles to relax, and lets the nervous system stop guarding.
What patients report
- Lower back pain that had been "background noise for years" reducing to occasional flare-ups
- Ability to sit, drive and sleep through the night without shifting to relieve pressure
- Confidence to return to activities they had quietly given up
The practical takeaway
A compressed disc from an accident years ago does not have to be a life sentence. If the pain has stayed the same despite time, medication and traditional rehab, the missing piece is usually motion — and specifically, motion at the joints the injury caused you to stop trusting.
