Why Your Hips Hurt After Sitting All Day — And What to Do About It
After a full day at a desk — or a long commute, or a day of back-to-back meetings — a lot of people notice something: their hips ache. Sometimes it’s a deep, achy tightness at the front. Sometimes a nagging pain through the outer hip or buttock. Sometimes it’s hard to even pinpoint exactly where it is.
If that sounds familiar, you’re not alone. Sitting-related hip pain is one of the most common complaints we see at our clinics at Bells Corners and Montreal Road — and it’s becoming more common as more Ottawa residents work from home, often in chairs and setups that weren’t designed with hours of daily use in mind.
The good news: this kind of hip pain is very treatable. And understanding why it develops in the first place is the first step toward getting rid of it.
Let’s break it down.
Why Sitting Is Hard on Your Hips
The hip is one of the most mobile joints in the body — built to move in multiple directions and support load across a wide range of positions. Prolonged sitting forces it into one position: flexed, static, and mostly unused.
Over time, a few things start to happen.
The hip flexors — the muscles that run from your lower spine and pelvis to your thigh — are held in a shortened position for hours at a time. Hold anything in a shortened position long enough, and it tightens. These muscles become chronically stiff and can begin to pull on the pelvis and lower back in ways that compound the problem.
At the same time, the glutes — the large muscles of your buttocks that are supposed to support and stabilize the hip — essentially go dormant during prolonged sitting. This is sometimes called “gluteal amnesia,” and while the term sounds a bit dramatic, the concept is real: muscles that aren’t being asked to work lose their ability to engage efficiently.
The result is a joint that’s stiff where it needs to be mobile, and weak where it needs to be strong. These are just two examples from a broader pattern of muscular adaptation that plays out differently across the larger muscle groups of the hip and lower body — which is precisely why a proper assessment matters before any treatment begins.
The Most Common Hip Pain Conditions from Sitting
Hip Flexor Tightness and Strain
The most straightforward complaint. When the hip flexors are chronically shortened from sitting, they become painful — especially when you stand up after a long session, walk briskly, or try to take a longer stride. The pain is usually felt at the front of the hip or in the groin area and can range from a dull pulling sensation to a sharper pinch when you extend the leg.
For most people this develops gradually. You notice it after long work sessions. Then you notice it in the morning. Then it starts affecting how you climb stairs.
Greater Trochanteric Bursitis (Hip Bursitis)
There’s a fluid-filled sac — called a bursa — on the outer point of your hip that cushions the bone against the soft tissue above it. When it becomes inflamed, you get pain on the outside of the hip that’s often sharp when lying on that side, walking on uneven ground, or climbing stairs.
Prolonged sitting, particularly with poor posture or with legs crossed, increases tension on the muscles that pass over this bursa and can contribute to irritation over time.
Piriformis Syndrome
The piriformis is a small but influential muscle deep in the buttock that helps rotate and stabilize the hip. When it becomes tight — which is common with prolonged sitting — it can irritate the sciatic nerve, causing pain, tingling, or numbness that radiates from the buttock down the back of the leg.
This is frequently mistaken for a disc or lower back problem. Getting the right diagnosis matters because these conditions respond to different treatments.
Referred Pain from the Lower Back or SI Joint
Not all hip pain comes from the hip. The sacroiliac (SI) joint — which connects the spine to the pelvis — and the lumbar spine itself can refer pain into the hip and buttock region. If you’ve been sitting in a compressed or misaligned position for extended periods, these structures can become stiff and irritated, and the hip is where you feel it.
A physiotherapist can help you distinguish between these fairly quickly. Getting clarity on the source makes a significant difference in how effectively it gets treated.
Why the Problem Is Often Somewhere Other Than Your Hip
Here’s what surprises a lot of patients: the hip is frequently where you feel the pain, but it’s not always where the problem starts.
Prolonged sitting affects the entire lower body — not just the hip in isolation. The lower back stiffens. The pelvis tilts forward or backward depending on your chair and habits. The core muscles responsible for stabilizing your trunk become less active. The ankles and feet, which spend hours pointed at the floor, lose mobility.
When you finally stand up and move, all of those changes show up in how load is distributed through your hips. A hip that’s already tight and weak then has to compensate for everything around it — and that’s when pain develops.
This is why treatment focused only on the painful hip — stretching it, resting it — tends to provide temporary relief at best. A proper assessment looks at the full picture: posture, pelvis, lumbar spine, and how you’re moving through your day.
What Physiotherapy Does Differently
When you come in with sitting-related hip pain, we’re not just looking at your hip.
A physiotherapist assesses your posture, pelvic alignment, hip mobility, and how your glutes and core are functioning — to identify not just what hurts, but why it’s hurting. From there, treatment typically includes a combination of:
Manual therapy — to release the stiff joints and soft tissues that have been locked in position, restoring movement and reducing pain quickly.
Targeted exercise — to rebuild the support system the hip relies on. This is the part that keeps the pain from coming back.
Ergonomic guidance — because even the best treatment is undermined if you return to the same setup. Small adjustments to chair height, monitor position, and how often you move throughout the day can make a measurable difference.
A practical activity plan — so you know exactly how much activity is appropriate during recovery, what to prioritize, and how to rebuild without aggravating symptoms.
The goal isn’t just to relieve the pain you have now. It’s to make sure you’re not back in six months with the same problem.
Does It Mean You Need to Stop Sitting?
Not entirely — that’s not realistic for most people. But it almost certainly means sitting differently and less continuously.
Research consistently shows that breaking up prolonged sitting is more effective than trying to optimize your posture and stay still. A short walk, a standing break, or a few hip mobility movements every 45 to 60 minutes can significantly reduce the load accumulation that leads to pain.
A physiotherapist can give you a clear, practical answer for your specific situation — and a plan that works with your actual schedule.
Simple Things You Can Do Right Now
While you’re waiting for an assessment, or if your symptoms are mild, these are reasonable starting points:
Set a movement timer. Every 45–60 minutes, stand up and walk for two to three minutes. You don’t need a formal stretch — just changing position breaks the accumulation cycle.
Check your chair height — and consider an ergonomic assessment if you have access to one. Your hips should be at roughly the same height as your knees, with your feet flat on the floor. If your workplace offers an ergonomic assessment, it’s worth taking — small adjustments to your setup can meaningfully reduce the load on your hips over the course of a day.
When to See a Physiotherapist
Consider booking sooner rather than later if:
- The pain is present when you wake up, not just after sitting
- It’s affecting how you walk, climb stairs, or move through daily activities
- You have numbness, tingling, or pain radiating down your leg
- You’ve had this before and it keeps returning
- Symptoms haven’t improved after two to three weeks of self-management
Hip pain that gets dismissed as “just from sitting” can become a more persistent problem when the underlying weakness and stiffness aren’t addressed. Catching it early means a faster recovery and less disruption to your day.
