If you have pain on one side of your lower back and you notice yourself standing or moving a little off to one side, pay attention to which way you’re shifting.
Most people shift away from the painful side.
This is your body trying to protect you by unloading pressure from that area. It’s called an antalgic shift, and it’s often where the problem really starts to grow.
The Shift Leads to a Hip Hike
When your body shifts away from pain, the hip on the painful side usually lifts or hikes upward.
One of the main muscles involved is the quadratus lumborum, or QL. It runs from your pelvis to your lower ribs and helps stabilize your spine.
As your body shifts away from the painful side, the QL on that side contracts to hold the hip up and keep you in that position. Over time you start living in that pattern. The muscle shortens and tightens, and instead of protecting your back, it begins compressing the same area you were trying to avoid stressing in the first place.
What Feels Better in the Moment Can Make It Worse
If your pain is nerve-related, you might notice that slightly bending toward the painful side actually feels better. That’s part of why this pattern sticks.
Your body finds a position that is shifted away from the pain and slightly flexed back toward it, and it parks there. That position can temporarily reduce nerve irritation, so the brain learns it fast and starts defaulting to it.
But it is not fixing anything.
The muscles on that side — the QL, psoas, and lower back muscles — stay shortened to hold that position. What started as a way to stay comfortable becomes a pattern that keeps the area compressed. The same position that felt better in the moment is eventually the thing keeping the problem going.
When the Glute Stops Doing Its Job
On the painful side, the glute often stops working the way it should. This isn’t always about weakness — the muscle can still feel active, but it’s no longer stabilizing the hip the way it needs to. It’s firing without functioning properly.
When that happens, the lower back takes over. It’s not built to handle that role full time, so it gets overworked and fatigued, which puts more pressure through the spine and feeds right back into the original problem.
How the Cycle Builds
- Left untreated, the pattern usually looks like this:
- Pain on one side → you shift away from it
- The hip on the painful side hikes up → muscles tighten and shorten
- You settle into a flexed, compensated posture → the body adapts to it
- The glute on that side stops stabilizing properly
- The lower back takes over → more compression, more irritation
Where a Heel Lift Can Come In
This compensation pattern can sometimes show up as what looks like a leg length difference — but it’s usually not a true difference in bone length. It’s the pelvis sitting unlevel because of how the body has been compensating.
Even when there is a real structural difference, a heel lift isn’t about correcting leg length. It’s about reducing the compensation pattern your body is relying on. A small lift under the right foot can help level the pelvis, reduce the need to shift and counterbalance, and take pressure off the lower back. It’s one tool for changing the input your body is working with.
How You Start Fixing It
The key is not just chasing the pain. You have to address the pattern.
That means loosening the muscles that have become overly tight, especially through the side of the lower back and hip. It means re-engaging the glute so it can actually stabilize the hip again instead of letting the lower back do the work. And it means working back toward a more neutral, balanced position before you start loading the spine with any serious training.
The goal is simple. Give your body a new default — one that isn’t built around protecting a position it learned from pain.
