Hip Bursitis in Runners

If you're feeling a sharp, burning pain on the outside of your hip — especially when you roll onto that side at night or climb stairs — you're likely dealing with hip bursitis. It's one of those injuries that can make even simple daily movements uncomfortable. But it's also one that responds really well to the right adjustments, and most runners can work through it without a long layoff.

What's Going On

On the outside of your hip, there's a bony prominence called the greater trochanter. You can feel it if you press into the side of your hip. Sitting between that bone and your iliotibial (IT) band is a small, fluid-filled sac called the trochanteric bursa. Its job is simple: reduce friction as the IT band slides back and forth over the bone every time you move your leg. Think of it as a tiny cushion that keeps things running smoothly.

The problem is that running asks this bursa to do its job thousands of times per session. When friction increases — because the IT band is tight, the hip stabilizers are weak, or you're running on surfaces that load one side more than the other — the bursa becomes inflamed. That inflammation is what produces the sharp, localized pain on the outside of your hip.

The good news is that bursitis is an irritation issue, not a structural one. You haven't broken anything. The bursa is inflamed and angry, and the path forward is about reducing the friction that's causing the problem while building the hip strength to keep it from coming back.

Why This Happens

• Cambered roads — if you always run on the same side of a sloped road, one hip is consistently working harder than the other. That asymmetric loading adds up over time.
• Weak hip abductors — your gluteus medius controls pelvic stability when you're on one leg (which, in running, is every single stride). When it's weak, the pelvis drops on the opposite side, increasing friction at the bursa.
• Tight IT band — a stiff IT band creates more pressure and friction as it slides over the trochanter with each stride.
• Sudden mileage increase — more miles mean more repetitions before your tissues have had time to adapt. The bursa gets overloaded before it's ready.
• Lying on the affected side — direct pressure on an already inflamed bursa keeps the irritation cycle going, especially during sleep.
• Cross-leg sitting — this position compresses the lateral hip structures and can aggravate an already sensitive bursa.

How to Recognize It

• You'll feel a sharp or burning pain right on the outside of the hip, often directly over the bony prominence.
• Lying on the affected side at night is typically painful — many runners first notice bursitis because it disrupts their sleep.
• You might notice an ache when climbing stairs, getting up from a low chair, or walking after sitting for a while.
• Pressing directly on the outer hip bone will be tender.
• The pain may radiate down the outside of your thigh, though it usually stays localized around the hip.

When to Get Help

Give this two to three weeks of consistent management — strengthen the hip abductors, stay off cambered surfaces, avoid sleeping on that side, and keep your running on flat terrain. If it's not clearly improving in that window, or if you notice any swelling around the hip, it's time to see a professional. Chronic bursitis can benefit from corticosteroid injection or targeted physical therapy, and getting the right diagnosis early makes treatment more effective.

Watch for these red flags:

• Pain that worsens despite rest and strengthening
• Visible swelling on the outside of the hip
• Pain that spreads or changes character significantly
• Symptoms in both hips simultaneously

How to Adjust Your Training

Mild

You can keep running, but change where and how. Ditch the cambered roads and stick to flat surfaces, or alternate which side of the road faces traffic on each run. Start a hip abductor strengthening program right away — clamshells, side-lying leg raises, and banded lateral walks are your best friends here. These address the root cause, not just the symptom.

Moderate

Stay on flat surfaces and dial back your volume. This is a good time to invest in your hip strength — side-lying leg raises, clamshells, band walks, and single-leg bridges will help stabilize the pelvis and reduce the friction that's causing the problem. Avoid sleeping on the affected side (a pillow between your knees helps), and skip any workouts that spike the pain.

Severe

If it's not improving with consistent home management, get it looked at. A sports medicine doctor or physiotherapist can confirm the diagnosis and discuss options like injection therapy or hands-on treatment. Don't push through severe bursitis hoping it will resolve — addressing it now is faster than dealing with a chronic version down the road.

Staying Ahead of It

• Flat running surfaces — avoid cambered roads, or alternate directions regularly so neither hip is consistently overloaded. Running on a track or flat path is ideal when your hips are sensitive.
• Hip abductor strengthening — side-lying leg raises, clamshells, and band walks should be a regular part of your routine. Strong hip stabilizers are the single best defense against bursitis.
• IT band management — foam roll the quad and lateral thigh above and below the hip, but avoid rolling directly on the bursa itself. That just adds more pressure to an already irritated spot.
• Sleep position — if you're a side sleeper, use a pillow between your knees to keep the hips aligned and reduce pressure on the outer hip.
• Gradual mileage builds — respect the 10% rule when increasing your weekly volume. Your tissues need time to adapt to new loads, and the bursa is no exception.

The Bottom Line

Hip bursitis is a friction and load problem, not a structural one. That means the solution is in your hands: strengthen the hip stabilizers, reduce the irritation, and be smart about your running surfaces. Most runners see significant improvement within a few weeks of consistent management. Stay patient, stay consistent with the strength work, and you'll be back to pain-free running before long.
