Hip Bursitis: Why Your Outer Hip Hurts and How to Fix It

The Outer Hip Pain Problem

Pain on the outside of the hip is extremely common—especially in women over 40, runners, and people who suddenly increase their activity. You lie on that side and it aches. Climb stairs and it flares. Sometimes it radiates down the outer thigh.

For decades, this was called "hip bursitis" or "trochanteric bursitis." Doctors assumed the bursa (a fluid-filled sac) over the bony prominence of the hip was inflamed.

But here's the thing: research now shows that most "hip bursitis" isn't actually bursitis at all.

Greater Trochanteric Pain Syndrome (GTPS)

The modern understanding is that outer hip pain is usually a tendon problem—specifically, the gluteal tendons that attach near the greater trochanter (that bony bump on the outside of your hip).

This condition is now called Greater Trochanteric Pain Syndrome (GTPS), which encompasses:

  • Gluteal tendinopathy (the main culprit in most cases)
  • Bursitis (sometimes present, but rarely the primary problem)
  • Gluteal tears (in more severe cases)
  • Why does this matter? Because treating bursitis is very different from treating tendinopathy. If you're doing the wrong thing, you won't get better.

    What Causes GTPS?

    Compressive Loading

    The gluteal tendons wrap around the greater trochanter. Certain positions compress these tendons against the bone:

    Lying on your side - Direct compression of tendons against the bone

    Standing with hip hitched - Shifting weight to one side compresses that hip

    Crossing legs - Compresses the outer hip structures

    Sitting with knees together - Creates sustained compression

    Tensile Overload

    The gluteal muscles and tendons can also be overloaded by:

  • Sudden increase in walking/running
  • Hill climbing or stairs
  • Single-leg activities
  • Weakness requiring tendons to work harder
  • Risk Factors

  • Female sex (3-4x more common in women)
  • Age 40-60
  • Sedentary lifestyle followed by activity increase
  • Weakness in hip abductors
  • Wide pelvis (increases the angle of pull)
  • Low back pain (often associated)
  • Symptoms

    Classic GTPS presentation:

  • Pain over the outside of the hip
  • Worse when lying on that side (often wakes you at night)
  • Worse climbing stairs or walking uphill
  • Pain with prolonged standing
  • May radiate down the outer thigh (but not past the knee)
  • Tender to press on the bony prominence
  • The Compression Problem

    Here's the counterintuitive part: many common "treatments" actually make GTPS worse.

    Stretching the IT band - Increases compression of gluteal tendons

    Foam rolling the outer hip - Direct compression on irritated tendons

    Pigeon pose - Compresses the tendons against the bone

    Lying on the affected side - Sustained compression

    If you've been stretching and foam rolling your outer hip without improvement (or with worsening symptoms), this is likely why.

    Evidence-Based Treatment

    Step 1: Reduce Compression

    Sleep positioning

    Don't lie on the affected side. If you're a side sleeper, lie on the opposite side with a pillow between your knees. Or sleep on your back with a pillow under your knees.

    Sitting posture

    Avoid crossing legs. Sit with knees slightly apart. Use a cushion if chairs are hard.

    Standing posture

    Don't hang on one hip. Keep weight even. Avoid prolonged standing when possible.

    Stop stretching into compression

    No IT band stretches, no pigeon pose, no foam rolling the outer hip. These feel like they should help but typically don't.

    Step 2: Progressive Loading

    This is the most important part. Gluteal tendinopathy responds to gradual, progressive loading—not rest, not stretching.

    Isometric exercises (start here)

    Isometrics involve muscle contraction without movement. For GTPS:

  • Side-lying with pillow between knees, press top knee into pillow (30-45 seconds, multiple times daily)
  • Standing, press outside of knee against wall (30-45 seconds)
  • Isometrics often provide pain relief while building tendon tolerance.

    Isotonic exercises (progress to)

    Once isometrics are comfortable:

  • Side-lying hip abduction (leg lifts)
  • Standing hip abduction with band
  • Single-leg stance holds
  • Step-ups (affected leg leading)
  • Functional exercises (final progression)

  • Single-leg squats
  • Lateral band walks
  • Running (if that's your goal)
  • Step 3: Address Contributing Factors

    Core and hip stability

    Weakness in the core and hip stabilizers often contributes to gluteal tendon overload. A comprehensive program addresses the whole chain.

    Load management

    If you increased activity recently, you may need to temporarily reduce volume while building tendon capacity.

    Weight management

    Higher body weight increases load on hip structures. Even modest weight loss can help if applicable.

    Timeline Expectations

    Gluteal tendinopathy typically takes 3-6 months of consistent work to resolve. Some key points:

  • Pain relief from isometrics can be quick (days to weeks)
  • Building tendon capacity takes months
  • Returning to full activity is gradual
  • Relapses are common if you progress too fast or return to compressive habits
  • What About Injections?

    Corticosteroid injections are commonly offered for "hip bursitis." The evidence is mixed:

    Short-term: Injections can reduce pain for weeks to a few months

    Long-term: Studies show exercise is superior to injections for lasting results

    Risk: Repeated injections may weaken tendons

    Injections might be appropriate for severe pain that prevents you from exercising, but they're not a standalone solution.

    When Is It Something Else?

    Outer hip pain isn't always GTPS. Consider other causes if:

    Pain radiates past the knee - Could be referred from spine

    Groin pain is prominent - Could be hip joint problem (arthritis, labral tear)

    Catching or locking - Suggests mechanical hip problem

    No tenderness over greater trochanter - Source may be elsewhere

    Doesn't respond to GTPS treatment - Time to investigate further

    An accurate diagnosis matters. Hip joint problems require different treatment than tendinopathy.

    Key Exercises

    Isometric Hip Abduction (Side-lying)

    Lie on your back or unaffected side with pillow between knees. Press top knee into pillow without moving. Hold 30-45 seconds. This builds tendon tolerance without compression.

    Standing Wall Press

    Stand sideways near a wall, affected side toward wall. Press outside of knee into wall. Hold 30-45 seconds. Great for pain relief.

    Side-lying Hip Abduction

    Lie on unaffected side. Lift top leg toward ceiling, keeping it slightly behind you (not forward). Control the descent. Start with 10-15 reps, progress as tolerated.

    Clam Shells (Modified)

    Lie on unaffected side with knees bent. Lift top knee while keeping feet together. Avoid rotating pelvis. This targets gluteus medius with less compression than traditional positioning.

    Single-Leg Stance

    Stand on affected leg for 30-60 seconds. Keep pelvis level (don't drop opposite hip). This builds functional hip stability.

    The Bottom Line

    Outer hip pain labeled as "bursitis" is usually gluteal tendinopathy. The treatment that works is:

    1. Reduce compression (stop stretching/rolling, fix sleep position)

    2. Progressive loading (isometrics → isotonics → functional)

    3. Patience (3-6 months for full recovery)

    Stop doing the things that feel like they should help but don't. Start doing the exercises that actually build tendon capacity. Give it time.
