If Rolling Over in Bed Wakes You Up in Pain, You're Not Alone
For many pregnant women, it's not falling asleep that's the problem, it's staying asleep.
One of the most common complaints in the second and third trimesters is a sharp, aching, or grinding pain in the pelvis or hips when turning over in bed. Some women describe it as a shooting pain through the front of the pelvis. Others feel it more as a deep ache in the back, hips, or thighs that spikes with every position change.
What's causing it and more importantly, what can you do about it?
What Is Pelvic Girdle Pain (PGP)?
Pelvic girdle pain (PGP) sometimes called symphysis pubis dysfunction (SPD) is pain felt around the front, back, or sides of the pelvis during pregnancy. It can also radiate into the hips, thighs, groin, or lower back.
It's extremely common. Research indicates that around 1 in 5 pregnant women experience pelvic girdle pain to some degree, with symptoms ranging from mild discomfort to significant mobility challenges.
PGP occurs when the joints of the pelvis which are held together by ligaments begin to move unevenly or become less stable. During pregnancy, hormonal changes cause ligaments throughout the body to soften and become more flexible in preparation for birth. Combined with the added weight of a growing bump and the shifting of your centre of gravity, this can place considerable strain on the pelvic joints.
Why Rolling Over Hurts So Much
Rolling over in bed feels like a simple movement, but it involves a complex sequence of actions in the pelvis particularly when you're pregnant.
When you roll without technique, you tend to:
- Keep your legs extended and apart
- Lead with the upper body while the lower body lags behind
- Create a twisting, asymmetrical movement through the pelvis
- Allow the legs to "fall open" as you transition from one side to the other
Each of these movements places significant shear force across the pelvic joints especially the symphysis pubis at the front and the sacroiliac joints at the back. When those joints are already sensitised or unstable, even small asymmetric movements can trigger sharp, significant pain.
The goal of any technique for rolling over with PGP is to minimise the separation of the knees and reduce asymmetric loading through the pelvis, essentially moving your body as one connected unit rather than in parts.
The Technique That Makes the Biggest Difference
Step-by-Step: How to Roll Over in Bed with Pelvic Pain
This is the technique recommended by physiotherapists and pelvic health specialists for reducing pain during nighttime position changes:
Step 1: Bring your heels close to your bottom
Before you do anything else, bend your knees and slide your heels up toward your bottom so your feet are flat on the mattress and your knees are pointing up. This is the most important step and the one most women skip.
Why does it matter? When your legs are extended, rolling over requires your pelvis to rotate through a large range of motion with significant leverage. Bringing your heels up shortens this lever arm dramatically. Your knees and hips are now in a bent, loaded position which means the muscles around the pelvis can assist the movement rather than being passive as your joints are dragged through it. The load on the symphysis pubis and sacroiliac joints is significantly reduced, and the movement becomes far more controlled.
Step 2: Squeeze your knees together
Before rolling, bring your knees together so they're touching or as close as comfortable. Keeping the knees together throughout the roll is critical as it prevents the pelvis from opening asymmetrically and reduces shear force across the pelvic joints. Think of your legs as one unit for this movement.
Step 3: Gently engage your core and pelvic floor
Take a breath in, and as you breathe out, gently draw in your lower abdominals and lightly activate your pelvic floor muscles as though you're very gently bracing. This creates internal support around the pelvic joints before you move, rather than relying on the joints themselves to handle the load.
Step 4: Move your shoulder and hip together in one motion
Now roll. Move your shoulder and hip at the same time, as one unit. Avoid leading with just your upper body or just your hips try to keep them moving together. This smooth, synchronised roll means the pelvis transitions as a single structure rather than twisting through the movement.
Step 5: Lower your knees slowly to the new position
Once you've rolled to your new side, gently lower your knees together to the mattress before separating them into a comfortable position. Don't let them fall apart.
Why the Heel Position Is So Important
The step of bringing your heels close to your bottom before rolling deserves its own explanation because it makes such a significant difference and isn't always intuitive.
When your legs are straight or only slightly bent, the weight of your legs acts as a long lever against your pelvis. As you try to roll, your legs lag behind your upper body, creating a twisting strain through the pelvis that directly stresses the very joints that are sensitised in PGP.
By bending your knees and bringing your feet flat to the mattress before rolling:
- You shorten the lever arm of your legs significantly, so there's far less rotational force on the pelvis
- Your hip and thigh muscles are in a position to actively contribute to the movement
- Your knees can stay together more easily throughout the roll
- The whole movement requires less effort and creates far less joint stress
Many women find that this one adjustment alone reduces rolling pain noticeably, even before adding other techniques. It's a small change that takes very little effort, but the biomechanical difference is meaningful.
Other Tips to Reduce Pelvic Pain at Night
Wear a support belt or shorts during the day A pelvic support belt or pregnancy support shorts worn during the day helps stabilise the pelvis while you're active which can reduce how sensitised the joints are by the time you get into bed. There's good evidence that pelvic support garments reduce PGP-related pain and improve function.
Slow down before bed Activities that load the pelvis asymmetrically - climbing stairs, and walking for extended periods can leave the joints more irritated by bedtime. In the hours before sleep, move slowly and symmetrically, and avoid anything that triggers your pain.
Get out of bed mindfully too Rolling out of bed follows the same principles as rolling over. Bring your heels up, keep your knees together, roll to your side, then drop your legs over the edge and push yourself up with your arms. Avoid sitting straight up from lying, it creates significant asymmetric strain through the pelvis.
When to See a Pelvic Health Physiotherapist
If pelvic pain at night is significantly impacting your sleep, daily function, or ability to walk comfortably, it's important to seek professional support. Most women find significant improvement with the right guidance and for the majority, symptoms resolve after birth.
In New Zealand, you can ask your midwife or GP for a referral to a physiotherapist who specialises in pelvic health.
Final Thoughts
Pelvic pain when rolling over at night is one of the most disruptive and least talked about parts of pregnancy sleep.
But there's a lot you can do about it, starting tonight.
A small change in technique; bending your knees, bringing your heels toward your bottom, keeping your knees together, and moving as one unit can make a meaningful difference to how much pain you experience during every nighttime position change.
You don't have to white knuckle your way through pregnancy sleep.
Better technique, better support, and the right advice can help you rest more comfortably and wake up ready for the day ahead.
