KEY TAKEAWAYS
- A tight quadratus lumborum (QL), the muscle just above the hip bone in the lower back, is most often caused by prolonged sitting, one-sided bag carrying, and pelvic misalignment.
- The most effective self-treatment is myofascial release: lie on a firm massage ball or softball placed above the hip bone and hold steady pressure on tender spots for 2 to 5 minutes, rather than rolling around.
- QL tightness can mimic sciatica, so a professional diagnosis is needed to tell the two conditions apart.

What is QL and where it is located?
The quadratus lumborum, or QL, is a deep muscle that runs along each side of your lower back, from the bottom of your rib cage down to the top of your hip bone (the iliac crest). It’s one of the main muscles that stabilizes your spine and pelvis as you stand, walk, and shift your weight from side to side. Because it works constantly to keep your low back steady, a tight QL muscle is a common source of one-sided low back pain and stiffness after a long day of sitting or standing.
Symptoms of QL muscle pain
Quadratus lumborum pain doesn’t always feel the same from person to person, but a few signs point specifically to the QL rather than another back muscle:
- Deep, aching pain on one side of the low back, just above the hip
- Pain that gets worse when standing up from a seated position or getting out of bed
- Stiffness or a “locked up” feeling first thing in the morning
- Pain that spreads into the hip, groin, or upper glute
- A noticeable pull to one side when standing, or one hip sitting higher than the other
Quadratus Lumborum Muscle Trigger Points
A quadratus lumborum trigger point is a small, hyperirritable knot within the muscle fibers that can refer pain to areas beyond the low back itself, including the hip, groin, and upper glute. These trigger points commonly form deep in the QL, close to where it attaches at the hip and lower ribs, which makes them harder to reach with a simple stretch alone. Left untreated, they tend to keep tightening the surrounding area, which is why consistent quadratus lumborum release work, whether through self-massage or in-office care, is usually needed to calm them down fully.
Common Causes of Quadratus Lumborum Muscle Pain
Most QL pain builds up gradually rather than happening all at once. The most common contributors include:
- Prolonged sitting, especially in chairs without good low-back support
- A leg-length difference or pelvic misalignment that forces the QL to work harder on one side
- Sleeping on your side without a pillow between your knees
- Repetitive bending, twisting, or lifting, especially lifting unevenly
- Weak core and glute muscles, which shift more of the stabilizing work onto the QL
- Sudden trauma, like a fall or an awkward twist
How do you fix a tight QL?
Fixing a tight QL usually comes down to three things working together: hands-on QL muscle massage to encourage QL muscle release, targeted stretching, and strengthening work so the muscle doesn’t tighten right back up. Here’s how to approach each one.
Self massage
Use a large massage ball or softball, place it right above the hip in that muscle area, and use your body weight while lying on the floor to apply pressure. While lying on your back, find the spot by raising up off of the hip bone and then placing the ball right under there.
This particular muscle can be tender, so you can moderate how much pressure you’re putting on it by how much you lean back. You could even prop up your upper body a bit to take some of the pressure off at first. After a while, you do want to be able to put quite a bit of pressure on it.
Be careful to avoid the hip bone and the spine; you’re just in that muscle portion in between both of those structures. Because this is a myofascial release, you’re not rolling around a lot. You’re just using the pressure of the sphere to go right into the muscle and the fascia, and you’re hanging out there for two to five minutes and letting the area dissipate. If it feels really good after just 30 seconds, you can ever so slightly roll around, find another tender spot, and hang out there for the full two to five minutes. Do this on both sides.

Stretch
Knowing how to stretch quadratus lumborum muscles properly means moving your torso in the opposite direction of the tightness, away from the side-bent, seated posture that caused it in the first place. Try these three stretches:
- Seated side bend: Sit tall, reach one arm overhead, and lean away from the tight side until you feel a stretch along your low back and ribcage. Hold for 20-30 seconds and repeat two to three times per side.
- Standing side reach: Stand with feet hip-width apart, plant one hand on your hip, and reach the opposite arm up and over toward the tight side. Hold for 20-30 seconds, breathing into the stretch rather than bouncing.
- Child’s pose with a side walk: From a kneeling position, walk both hands over to one side while sitting your hips back toward your heels. This adds a gentle rotational stretch to the QL that a standard child’s pose doesn’t reach.
Strengthening the Muscle to Prevent Further Injuries
Stretching loosens the QL, but strengthening it keeps it from tightening back up. These three exercises build the stability the muscle needs:
- Side plank: Lie on your side, prop yourself up on your forearm, and lift your hips off the floor, keeping a straight line from shoulders to feet. This directly loads the QL on the down side, building the endurance it needs to stabilize your pelvis throughout the day.
- Bird dog: On hands and knees, extend one arm and the opposite leg at the same time while keeping your low back still and level. This teaches your core and QL to work together to control rotation, which is what breaks down during long periods of sitting.
- Suitcase carry: Hold a moderately heavy weight in one hand and walk a short distance while keeping your torso upright and level. Your QL on the opposite side has to fire hard to stop you from tipping sideways, which builds real-world stabilizing strength.

Frequently Asked Questions
What makes the QL muscle tight?
The quadratus lumborum tightens from side-sleeping without support, carrying bags on one side, or compensating for hip imbalances. Prolonged sitting and poor core strength also contribute significantly.
QL tightness often indicates pelvic misalignment, which our gentle adjustments can effectively address.
How do I release QL trigger points?
Lie on your side with a tennis ball under your lower back, between ribs and pelvis. Breathe deeply, allowing gentle pressure for 60-90 seconds. Move the ball slightly to cover the entire muscle.
Professional trigger point release combined with chiropractic care provides faster, more complete relief at Healthworks.
Can tight QL cause sciatica symptoms?
Yes, QL tightness can mimic sciatica by compressing nerves and referring pain down your leg. Distinguishing true sciatica from QL syndrome requires a professional diagnosis for proper treatment.
Our F3 examination differentiates QL tightness from true sciatica to guide targeted treatment.
Where is the QL muscle located?
The quadratus lumborum sits deep in your low back, on either side of your spine, running from the bottom of your last rib down to the top of your hip bone. You can’t see it or easily feel it through the surrounding muscles, which is part of why QL pain is often mistaken for a hip or SI joint problem.
A chiropractic exam can confirm whether the QL, rather than a nearby joint, is the true source of your pain.
How should you sleep with QL pain?
Sleep on your side with a pillow between your knees to keep your hips level, or on your back with a pillow under your knees, since either position takes pressure off a tight QL. Avoid sleeping on your stomach, which rotates the low back and pelvis in a way that tends to worsen QL tightness.
If you’re still waking up stiff despite adjusting your sleep position, that usually means the muscle needs active release, not just better support at night.
How do you strengthen the QL muscle?
Side planks, bird dogs, and suitcase carries are the most effective ways to strengthen the QL, since all three train it to stabilize your spine and pelvis the way it’s meant to. Start with two to three sets of each, two to three times a week, and only add load or hold time once the movement feels stable and pain-free.
We can also assess whether a hip or pelvic imbalance is causing one QL to overwork before you build a strengthening routine around it.
Can a chiropractor help with a tight QL?
Yes. Chiropractic care addresses the hip and pelvic misalignments that often keep the QL tight in the first place, rather than just temporarily easing the muscle the way a stretch or massage does on its own. Combining an adjustment with the self-massage and stretches above tends to bring longer-lasting relief than either approach alone.
At HealthWorks, we check for pelvic and hip alignment issues as part of every low back pain visit, including QL tightness.
