If you’ve been dealing with chronic back pain for months or years, you’ve probably noticed something frustrating: the obvious “fixes” don’t really work. You stretch. You buy a better chair. You take pain relievers. The pain backs off—then comes right back, like it’s been hiding around the corner waiting.
Here’s why: most chronic back pain isn’t caused by the thing people think is causing it. The real drivers are often quiet, invisible, and easy to overlook. At Actus Chiropractic in Brentwood, CA, Dr. Val Tompkins sees the same hidden patterns over and over—in office workers, weekend warriors, new parents, and retirees alike.
This guide unpacks the hidden causes of chronic back pain most people ignore, why they matter, and what to do about them so the pain finally stops cycling back.
Why Chronic Back Pain Keeps Coming Back
Acute back pain—the kind that hits suddenly after lifting something or sleeping wrong—usually has a clear story. Chronic back pain is different. It often lingers because the root cause was never identified or addressed. Painkillers and rest can quiet the symptom, but if the underlying mechanical pattern is still there, the pain returns the moment you go back to your normal life.

7 Hidden Causes of Chronic Back Pain Most People Ignore
1) A Stiff Mid-Back That Forces the Low Back to Overwork
Your thoracic spine (mid-back) is built for rotation and extension. When it stiffens up—usually from sitting and screen time—the lumbar spine and hips have to compensate. Suddenly the low back is taking on motion it was never designed to provide. Over months and years, this creates wear, irritation, and chronic ache.
The clue: Your low back hurts, but you also feel tight between your shoulder blades and have trouble taking a deep breath.
2) Hip Stiffness You Don’t Even Notice
The hips are supposed to move freely in every direction. When they don’t, the low back takes the hit. Tight hip flexors, restricted hip rotation, and “sleeping” glutes are one of the most common patterns Dr. Tompkins sees in chronic back pain.
The clue: Your back is worse after sitting, getting out of the car, or first thing in the morning.
3) Poor Sleep Position
You spend roughly a third of your life in bed. If your pillow, mattress, or sleep position is loading your spine wrong, you’re starting every single day in a hole. People often blame their bed last because they think pain “should” come from activity.
The clue: You wake up feeling stiffer than when you went to bed. For specific tips, see our guide to the best sleeping positions for back pain.
4) Core Weakness (Not What You Think It Is)
A “weak core” doesn’t mean you can’t do crunches. It means your deep stabilizing muscles—transverse abdominis, diaphragm, pelvic floor, multifidus—aren’t doing their job. Without them, the spine has nothing to hold it steady during everyday movement.
The clue: Your back “tweaks” doing trivial things—bending to pick up a sock, sneezing, reaching for a seatbelt.
5) Stress and a Sensitized Nervous System
Chronic stress, anxiety, and poor sleep ramp up the body’s pain signaling. The same tissue irritation that used to be a 3 out of 10 now feels like a 7 out of 10. This isn’t “the pain is in your head”—it’s the pain is in your nervous system, which is real and treatable.
The clue: Pain flares with high-stress weeks even when nothing physical changed.
6) Old Injuries That Never Fully Healed
That fall years ago. The car accident in your twenties. The pulled muscle that “got better on its own.” Old injuries often leave behind altered movement patterns—and the body builds new habits around the old damage. Years later, the pain shows up somewhere new.
The clue: You can’t quite remember when this back pain started, or it feels weirdly disconnected from anything you did recently.
7) Too Much Stillness, Not Too Much Activity
The biggest hidden cause of all. Modern humans sit in the same position for hours, sleep in one position, and then wonder why the spine—which thrives on variety—starts to ache. Sustained stillness is more damaging than most “high impact” activity people assume is the culprit.
The clue: You feel worse on the days you “rest.” Movement actually makes you feel better.
How to Identify Your Real Drivers
Most chronic back pain isn’t one cause—it’s a combination. Identifying the mix matters. A skilled Brentwood chiropractor will look at:
- How each segment of your spine moves (and where it doesn’t)
- Hip and shoulder mobility
- Core activation and stability under load
- Your daily posture, sleep, and movement habits
- Old injuries and surgeries
- Stress, sleep, and overall health context
Without that bigger picture, treatments tend to chase the symptom and miss the cause.
How Chiropractic Care Addresses the Hidden Causes
At Actus Chiropractic, Dr. Val Tompkins addresses chronic back pain by treating why it keeps coming back, not just where it hurts. That looks like:
- Restoring joint motion in the spine, hips, and shoulders through targeted adjustments
- Releasing chronically tight tissues—hip flexors, glutes, lats, quadratus lumborum
- Reactivating sleeping stabilizers with simple, specific exercises
- Coaching daily habits—sleep position, sitting strategy, micro-movement
- Tracking progress with measurable changes in movement, not just pain levels

What You Can Do This Week to Start Helping the Hidden Causes
- Break up sitting. Set a timer for every 30–45 minutes and move for 60 seconds.
- Mobilize the mid-back. Try two minutes of cat/cow and open-book rotations daily.
- Free your hips. Add a 30-second couch stretch on each side and 10 hip circles per direction.
- Sleep neutral. Side sleepers: pillow between knees. Back sleepers: pillow under knees.
- Walk daily. 20–30 minutes, even split into chunks. It’s the most underrated back-pain tool we have.
- Sleep enough. Below 6 hours per night, pain sensitivity climbs.
FAQs: Hidden Causes of Chronic Back Pain
How do I know if my back pain has a hidden cause?
If you’ve tried the obvious things—rest, ice, stretching, pain relievers—and the pain keeps coming back, there’s almost always a hidden mechanical or lifestyle driver still in play.
Do I need imaging like an MRI?
Usually no, especially early on. Imaging is helpful when there are specific red flags or when conservative care isn’t producing results. Most chronic back pain responds to a thoughtful, conservative approach.
How long does it take to get long-term relief?
It depends on how long the pain has been there and how many hidden causes are involved. Many patients feel meaningful improvement within a few weeks, with steady progress over a few months.
Can I keep exercising?
In most cases, yes—and you should. Movement is medicine for chronic back pain. A good chiropractor will help you modify activities while you recover, not eliminate them.
Is chronic back pain ever permanent?
Pain itself rarely is. The patterns that drive it can be deeply ingrained but are almost always changeable with the right plan.
