QL pain is a deep ache on one side of your lower back that comes from the quadratus lumborum, a muscle beside your spine that works overtime when you sit, lift or stand on one leg, and QL massage can ease that tightness, though some one sided lower back pain needs a doctor first. Your lower back has two QLs, and only one of them is filing complaints.
The quadratus lumborum sits too deep to reach on your own, which is where a trained pair of hands helps. You can arrange trigger point massage therapy at home through Blys, so a sore back doesn’t have to sit in traffic to get help.
What Is QL Pain?
QL pain is pain that comes from the quadratus lumborum muscle, and it usually shows up as a deep, one-sided ache in the lower back. Knowing what the muscle is and where it lives makes the pain much easier to recognize.
Where Is the Quadratus Lumborum?
The quadratus lumborum, or QL, is a deep muscle on each side of your lower spine, running from your lowest rib and the bones of your lower back down to the top of your pelvis. You have one on the left and one on the right, and they sit underneath the bigger back muscles you can feel with your hands.
What Does the QL Do?
The QL helps hold your lower back upright, bends your trunk to the side and lifts one side of your hip when you walk. Think of it as the stagehand of your spine: you never notice it until something goes wrong. It works every time you sit, stand or move, so it rarely gets a real break.
What Does QL Pain Feel Like?
QL pain usually feels like a deep ache in the lower back, just to one side of your spine and above the top of your hip bone. It can spread to the hip, the buttock or the groin, and a tender spot you can press on is a common sign. Many people notice it most when they stand up from a chair, bend to the side or stand in one place for a while.
Why Does Only One Side of My Lower Back Hurt?
Only one side hurts because you have one QL on each side, and your habits rarely load both evenly. You lean on one hip, carry a bag on one shoulder, cross the same leg or sleep on the same side, and the QL on the busier side ends up with the extra work. That’s why one sided lower back pain so often points to the QL, although it’s not the only possible cause.
Sitting Through the Workday
Sitting keeps your hips bent and your lower back holding you upright, and the QL works as a stabilizer the whole time. If you sit a little crooked, leaning on one armrest or perching on one hip, the QL on that side works harder than its partner. Hybrid and remote work haven’t helped, because the couch isn’t lumbar support. Tight hips add to the problem too, since tight hip flexors from sitting can tug on the lower back and add to the load.
Lifting and Twisting
Lifting something awkward, twisting while you lift or hauling a heavy bag out of the trunk can overwork the QL in one go. The muscle stabilizes your spine while your arms and legs do the lifting, so a sudden or lopsided load asks it to work hard without warning. A weekend of yard work or moving boxes is a classic setup for QL pain by Monday.
Standing on One Leg and Carrying Things on One Side
Waiting for the microwave on one leg is a core workout nobody asked for. Resting your weight on one hip, holding a toddler on one side or wearing a backpack on one shoulder all ask one QL to do more than the other, and a backpack on one shoulder is a lopsided gym membership.
Commutes, Sleep and Other Everyday Causes
A long car commute with your back unsupported, a sleeping position that twists your lower back and a sudden sneeze with a twisted spine can all set off QL pain. The table sums up the usual suspects.
| Everyday cause | What it asks of the QL |
| Long hours of sitting | Hold your lower back upright for hours, often unevenly |
| Lifting and twisting | Stabilize the spine under a sudden or lopsided load |
| Standing on one leg or leaning on one hip | Work harder on one side than the other |
| A bag or backpack on one shoulder | Balance the weight, one side doing more |
| Long car commutes | Hold the spine steady with little movement |
| Sleeping in a twisted position | Stay slightly stretched or squeezed for hours |
Is It QL Pain or Something Else?
Lower back pain has many possible sources, and the QL is only one of them, so a quick comparison helps. Only a doctor or physical therapist can say what’s behind your pain, but the table shows the differences people most often describe.
| Possible source | Where it’s felt | What it usually feels like | What makes it worse |
| QL (muscle) | One side of the lower back, above the hip bone, sometimes the hip or buttock | A deep ache with a tender spot | Standing up, side bending, long sitting or standing |
| Sciatica (nerve) | Lower back and down the leg, often below the knee | Sharp, burning or tingling pain | Sitting, coughing or sneezing |
| Disc problem | Lower back, sometimes with leg symptoms | Sharp or deep pain, sometimes with numbness | Bending forward or lifting |
| Joint at the base of the spine | Low on one side near the top of the buttock | An ache or sharp pain | Stairs, standing on one leg or rolling over in bed |
| Kidney | One side, higher and deeper in the back | A constant ache that doesn’t change with movement | Nothing you do with your body, and often fever or urinary symptoms |
Signs That Point to QL Pain
QL pain is usually one sided, deep and tender to press, and it often eases a little when you change position. Side bending, standing up from a chair and standing on one leg often set it off. If that sounds like you, QL massage is a reasonable thing to ask about once you’ve checked with your doctor, and trigger point massage therapy is a common starting point.
QL Pain vs Sciatica
QL pain stays in the lower back, hip or buttock, while sciatica sends sharp, burning or tingling pain down the leg, often below the knee. If your pain travels down your leg, or you have numbness or tingling, tell your doctor before you arrange any massage. A massage therapist can’t diagnose which one you have, and the two can show up together.
One Sided Lower Back Pain That Isn’t Your Muscles
Not all one sided lower back pain comes from the QL, and kidney problems are one example of something that can feel like a back ache. Pain that sits high and deep on one side, doesn’t change when you move and comes with a fever, pain when you urinate or blood in your urine needs a doctor, not a massage. For the wider picture, the best type of massage for lower back pain depends on what’s behind the pain, which is one more reason to get the cause checked first.
Back Pain Red Flags: When to Call a Doctor or 911
Most lower back pain isn’t serious, but a few signs mean a doctor comes first, and this is the section most massage posts skip.
Call 911 for These Signs
Call 911 if back pain comes with chest pain or pressure, shortness of breath, feeling faint, a cold sweat, or sudden, severe pain with a tearing feeling. Don’t arrange a massage and don’t wait it out, because these signs need emergency care.
See a Doctor Before Any Massage for These Signs
See a doctor before any massage if your back pain comes with loss of control of your bladder or bowels, numbness around your groin or inner thighs, new weakness or numbness in your legs, a fever, blood in your urine or pain when you urinate. Also see a doctor if the pain follows a fall or injury, keeps getting worse, wakes you at night or doesn’t ease with rest, or if you’ve lost weight without trying.
What This Page Is and Isn’t
This page is general information about QL pain and massage, and it isn’t medical advice. It doesn’t diagnose the cause of your back pain, and it doesn’t promise that massage will fix it. Massage suits muscle tightness once a doctor has ruled out anything else, so check with your doctor first if you have any red flag or any doubt.
How QL Massage Works: Trigger Point and Deep Tissue
Quadratus lumborum massage works on a muscle that’s too deep to reach on your own, and two styles are the usual options.
Why You Can’t Reach Your QL Yourself
You can’t reach your QL yourself because it sits beneath other back muscles, at an angle your hands and a foam roller can’t get to comfortably. Reaching your own QL is like reading the back of your own T-shirt in a mirror: you know it’s there, and you still can’t get a good look. A massage therapist can have you lie on your side, find the edge of the muscle and apply steady pressure you couldn’t make yourself.
Trigger Point Massage for the QL
Trigger point massage holds steady pressure on a tender spot in the muscle until it eases, which is the technique at the heart of trigger point massage and how it works, and the QL often has one or two of them. The spot can feel like a sharp, deep ache while your therapist holds, then ease as they release, and it can send a dull ache toward the hip or buttock.
Deep Tissue Massage for One Sided Lower Back Pain
Deep tissue massage uses slow, firm strokes through the deeper muscle layers, and it suits a broad, stubborn ache along one side of the lower back. Your therapist builds the pressure slowly and checks in as they go, so you can ask for firmer or lighter at any point. If you’re not sure which style to choose, say so in your booking notes, and your provider can talk you through the options. The same slow, firm approach is the idea behind deep tissue massage for back pain.
| Style | What it involves | Suits |
| Trigger point massage | Steady pressure held on a tender spot | A sore spot you can point to |
| Deep tissue massage | Slow, firm strokes through deeper muscle layers | A broad, stubborn ache on one side |
What Happens in a QL Massage Session
A quadratus lumborum massage session is calmer and slower than most people expect, and it follows a predictable order.
Before the Session: The Conversation
Your therapist starts by asking where it aches, which side, what sets it off, how long you sit and what you do for work, plus anything your doctor has told you. Say if the pain travels down your leg or if you’ve had any red flag signs from the section above. Your answers decide which style your therapist uses and how firmly they work.
During the Session: Positions and Pressure
You usually lie on your side or face down with a pillow under your hips, and your therapist works on the QL with their thumbs, forearm or elbow. Please keep your underwear on and lie under a sheet or a towel, and your therapist uncovers only the area they’re working on. Expect firm, steady pressure that feels like a deep ache at the sore spot, never a sharp or frightening pain, and speak up if it’s too much.
After the Session: What to Do Next
Some people feel a little tender the next day, like after a new workout, and some feel looser right away. Move gently, keep to your normal routine and tell your therapist or doctor if the pain gets sharper or spreads. A short walk beats a long nap on the couch.
How Often Do People Get QL Massage?
Your doctor and your therapist decide how often makes sense for you, and it depends on how long the pain has been there and what keeps feeding it. On Blys you can set sessions to repeat and ask for the same provider each time, so the person arriving already knows your QL, your habits and what worked last time. A new strain and an ache you’ve carried for months need different plans.
Hips, Glutes and the QL: Why Your Therapist Looks Beyond the Lower Back
QL pain rarely travels alone, and your therapist often works on the hips and glutes as well as the lower back. Your hips and your QL are co-workers who never take the same break: when the front of the hip stays short from sitting, the lower back picks up the slack. Easing both gives the QL a better chance of settling, so if your hips feel stiff too, mention it in your booking notes and ask your therapist whether to include them, and look at massage options for hip pain for the styles that suit that area.
Small Changes to Your Desk, Your Lifting and Your Stance
Even great QL massage can’t undo eight hours of lopsided sitting by itself, so a few habits between sessions matter.
Desk Habits for a Happier QL
Sit with your weight even on both hips, keep your feet flat and bring your screen and keyboard close enough that you don’t twist or lean. Stand up and walk for a minute every so often, and turn a seated call into a walking one when you can. If you work from the couch, move to a chair with a firm back for at least part of the day, because sports massage for desk workers often starts with a sitting week just like yours.
Lifting Without Overworking the QL
Keep heavy things close to your body, bend your knees and hips and not only your back and avoid twisting while you lift. Split a heavy load into two lighter ones, and switch the side you carry bags on. A physical therapist can show you a lifting technique that suits your body and your job.
Standing and Carrying Habits
Stand with your weight even on both feet, swap the hip you rest on and wear a backpack on both shoulders or alternate sides. If you carry a child on your hip, switch sides often. Small changes spread the work across both QLs instead of burning out one.
Getting QL Massage at Home With Blys
A sore back wants the couch, not the car, and a therapist who comes to you makes that possible.
Why Home Works for QL Pain
When your lower back is sore, sitting in a car for the trip to a clinic and again on the way home is the last thing it wants. A session at home means you stay in your own space, and you can lie down on your own couch afterward. Bookings run from 6 am to midnight, seven days a week, so an evening session after work fits around a late finish.
What to Expect When Your Therapist Arrives
Your therapist brings the table, fresh linen, towels and massage oil or lotion, and you only need to clear about 6.5 x 6.5 feet of floor. You’re not charged until a provider confirms your booking, and same-day times depend on availability. A quiet room and a sturdy chair nearby are all the space you need.
What to Put in Your Booking Notes
Put which side of your lower back hurts, how many hours a day you sit, what sets it off and the style you’d like in your booking notes, whether trigger point or deep tissue. Add anything your doctor has told you, so your therapist arrives knowing what to focus on and what to avoid.
Once your doctor has seen your back, a session at home is an easy way to look after the muscle, and the car keys can stay on the hook.

People Also Ask: QL Pain and QL Massage
These are the questions people type into search once they suspect their QL is the culprit.
What does a QL spasm feel like?
A QL spasm usually feels like a sudden, tight, deep pain on one side of the lower back, and it can make standing up straight or bending to the side difficult. It can come on after lifting, twisting or a long sit. Severe or sudden pain with any red flag sign is a reason to see a doctor.
Can QL pain spread to the hip or groin?
Yes, QL pain can spread toward the hip, the buttock and sometimes the groin, because the muscle attaches near the top of the pelvis. A doctor or physical therapist can tell you whether pain in the hip comes from the QL or from the hip itself.
Does heat or ice help QL pain?
Many people find heat comfortable on a tight lower back, and some prefer ice, and either can be a reasonable thing to try for comfort. Ask your doctor or physical therapist what suits your situation, and don’t use either on skin that’s numb or injured.
Should I stretch a tight QL?
A gentle stretch can feel good for some people, but stretching a sore muscle hard can make it angrier, so ask a physical therapist to show you a stretch that suits you. Stop if you feel sharp pain, numbness or tingling.
Is a massage gun safe for the QL?
A massage gun can feel good on large, fleshy muscles, but the QL sits close to the spine and the kidneys, so keep pressure gentle, stay off the spine and ask a physical therapist before you use one on your lower back. Stop if you feel sharp pain or numbness.
How long does QL pain last?
It depends on what caused it and how long it’s been building, and a new strain can settle in a few days to weeks while an ache you’ve carried for months can take longer. See a doctor if it isn’t improving, keeps coming back or comes with any red flag sign.
