The hip "bursitis" that isn't bursitis.

Pain on the outside of your hip that ruins stairs, walks, and sleeping on your side has a name most doctors still get wrong — and the name matters, because it's the reason so many treatments only work for a while.

01The person this happens to

It usually starts small.

An ache on the outside of your hip after a long walk, or a twinge on the stairs. Then one night you roll onto that side in bed and it wakes you up — and from then on, that's the side you can't sleep on.

Months go by. You rest it; it calms down, then comes right back. Maybe your doctor called it hip bursitis and suggested ice and an anti-inflammatory. Maybe you got a cortisone shot, and for a few glorious weeks it was gone — until it wasn't.

If that story sounds familiar, you're in well-studied company. Pain over the bony point of the hip — what medicine now calls greater trochanteric pain syndrome (GTPS) — accounts for one in every five to ten hip-pain visits to a primary care doctor. It's most common in women between 40 and 60, and it has a well-earned reputation for outlasting every quick fix thrown at it.

Here's the part that changes everything: in most cases, it isn't really bursitis. And once you understand what it actually is, the whole frustrating history — the relief that wore off, the rest that didn't work, the stretches that made it angrier — finally makes sense.
02What it is

The bony bump, the tendons, and the cushion.

Feel the widest point of your hip — that hard knob of bone on the outside. That's the greater trochanter, part of your thigh bone. It's the anchor point for the tendons of your gluteus medius and gluteus minimus — the deep hip muscles that hold your pelvis level every single time you stand on one leg. Which is every single step you take.

Draped over that bone and those tendons is a thin cushioning sac called a bursa, and over everything runs the iliotibial band — a long strap of dense tissue from your pelvis to your knee.

So it's safe to say the greater trochanter area is actually several tissues all layered on top of each other — and historically, the bursa is the one that ended up getting the most attention.

For decades, pain here was blamed on the bursa: "trochanteric bursitis," an inflamed cushion. It's a tidy story. It's also, in most cases, not what's happening. When researchers actually looked — in surgical specimens, on MRI, under the microscope — the bursa was often quiet. The real problem, over and over, was the gluteal tendons themselves: frayed, disorganized, and worn down where they attach to the bone. The medical term is gluteal tendinopathy.

That's why the name changed from "trochanteric bursitis" to "greater trochanteric pain syndrome." And it's not academic hair-splitting. "-itis" means inflammation — and inflammation is treated by calming things down. Rest, ice, anti-inflammatories, cortisone. But a worn, stalled tendon isn't a fire to put out. It's a structure that has stopped repairing itself. Calming it down feels better for a while — and changes nothing about why it hurts.

If you've ever wondered why your hip keeps coming back after treatments that "worked," this is usually the answer: the treatment matched the old name, not the actual problem.
03Why it happens

Too much load, on a tendon that's become sensitive under it.

Every condition we treat comes down to the same two-part equation, and this one is a textbook case: a tissue under more load than it can recover from, slowly becoming sensitized.

For the gluteal tendons, the load that matters most isn't pulling — it's squeezing. Whenever your thigh crosses toward (or past) your body's midline — a position called adduction — the iliotibial band tightens over the greater trochanter and compresses the gluteal tendons against the bone underneath it. Tendons tolerate pulling well. They tolerate being crushed against bone while pulling much less well, especially where they attach.

LEVEL PELVISIT bandgreater trochanter+ gluteal tendonsDROPPED PELVISpelvis drops withevery stepband squeezes thetendons against bone
Level pelvis The deep hip muscles hold the pelvis steady on one leg. The IT band lies flat; the tendons just do their job.
Dropped pelvis Weak abductors let the pelvis dip with each step. The hip drifts into adduction — and the IT band squeezes the very tendons trying to do the work. Thousands of steps a day.

That loop is the engine of the whole condition: the weaker the tendons get, the more they're compressed; the more they're compressed, the weaker they get. It's why this condition so rarely fixes itself once it's established. And the compression doesn't only happen while you're moving — look at where it shows up in ordinary life:

Everyday positions that squeeze the tendon

Hanging on one hip

Pelvis dropped, thigh angled in — standing "at ease" is loaded standing.

Sitting with knees crossed

Or knees together, feet apart. Hours of quiet compression.

Sleeping on your side

Bottom hip pressed on the mattress; top hip drops across midline. Both sides lose.

Walking & stairs

If the pelvis dips, every step is a small squeeze — thousands of times a day.

Why you? Why now?

The usual triggers are load spikes and load changes: a new walking program, a hilly vacation, a fall, a season of long days on your feet — or sometimes nothing you can point to at all.

The 40–60 female pattern isn't an accident either: pelvic proportions that increase the resting angle of hip adduction, and hormonal changes around menopause that affect tendon quality, both stack the deck. Add the modern default of sitting — knees together, tendons compressed — and it's a common recipe.

None of that is a character flaw or an age sentence. It's mechanics — and mechanics can be examined, measured, and changed.

Why rest doesn't fix it

Rest removes the activity, but not the positions. You still sit, still sleep — and if the pattern that overloads the tendon lives in how your pelvis is controlled, you carry the problem into every step of your "rest."

Meanwhile a tendon that's deep into this process has often stopped trying to heal — the repair response has stalled. Take away the insult and you get quiet, not repair.

That's the dividing line that determines treatment: early, irritated tendons settle when you unload them. Late, stalled tendons usually need something that restarts the repair process. It's the same lesson Dr. Barton learned personally with his own Achilles tendons — he tells that story here.

04What can be done

The honest tour of your options.

This condition has something most don't: good head-to-head trials. Researchers have directly compared the common treatments and followed patients for a year or more. The results are worth knowing before anyone treats your hip — including us.

Cortisone injections

Real relief · wrong trajectory

Cortisone is the standard offer, and in the short term it works — trials show most people feel substantially better at around one month. But follow those same patients further out and the story inverts. In a 229-patient randomized trial, the injection group led everyone at one month — and by fifteen months had fallen behind every other group in the study, including people who just did home exercises. A large randomized trial in the BMJ found the same shape: education plus exercise beat a corticosteroid injection at eight weeks and at one year.

This is why "the shot wore off" is the most common sentence we hear about this condition. The shot treats the alarm. The loading problem that set off the alarm is still there — and repeated injections come with their own concerns for tendon tissue.

Stretching

The fix that backfires

This one surprises almost everyone. The outside of your hip feels tight, so you stretch it — usually by pulling the thigh across your body. Look at that position again: it's maximum adduction. You are pressing the sore tendon against the bone as hard as anatomy allows, and calling it therapy.

The tightness most people feel is the symptom of an irritated, compressed tendon — not its cause. Sports-medicine guidance is unambiguous here: iliotibial-band and crossed-leg stretches make gluteal tendinopathy worse. If a stretching routine has been failing you, that's not your fault. It was the wrong tool, applied to the wrong problem, in exactly the wrong direction.

Education + progressive strengthening

The proven foundation

The winning arm of that BMJ trial wasn't a device or a drug — it was teaching people the compression story you just read (which positions to avoid, how to sleep, how to manage load) and progressively strengthening the gluteal muscles so the pelvis stays level and the tendons are loaded in ways that build rather than squeeze.

Any honest treatment plan for this condition is built on this floor. Ours is too.

Shockwave therapy

Strong evidence · usually skipped

In the same three-arm trial, shockwave therapy outperformed both cortisone and home training at four months and remained among the best outcomes at fifteen — and a systematic review concluded shockwave outperformed both home training and corticosteroid injection for this condition in the short and long term. Greater trochanteric pain sits in the top tier of conditions where the shockwave literature is strongest, alongside plantar fasciitis and calcific shoulder tendinopathy.

Most patients have simply never been offered it — cortisone is faster to deliver and easier to bill.

Surgery

The last resort it should be

For the small group with true tendon tears or years of failed conservative care, surgical options exist and outcomes are generally good. Almost nobody with this condition should start there — and the research agrees.

05How we treat it at Peak

Find the stage. Change the load. Restart the repair.

Everything above converges on a simple treatment logic — the same loading model we apply to every tendon in the body.

1

The exam — including the check most hip evaluations skip

Not a glance-and-a-shot — an actual biomechanical exam. We confirm it's the gluteal tendons and not the hip joint, the low back, or something that needs imaging or a surgeon (and if it is, we say so — that's the deal). Then we stage the tendon honestly: irritated, struggling, or stuck. The stage — not the calendar, not a package — determines what happens next.

The pelvic distortion check

A distorted pelvis sits visibly asymmetric — most often showing up as an apparent short leg. Occasionally the leg really is shorter, but that's the rare case. Far more often, the pelvis is being pulled out of level by an imbalance at one of its anchor points:

Skeleton diagram highlighting uneven tension of the hamstring musclesUneven hamstrings
Skeleton diagram showing unequal leg lengthsTrue short legRare
Spine diagram highlighting restricted lumbar facet joint mobilityFacet joint tightnessLow back
Body diagram highlighting restricted lumbar fascia mobilityLumbar fascial tension
Remember the engine of this condition — a pelvis that won't stay level. In our experience, a distorted pelvis does the same thing from a standing start: one side begins every stride already tilted, so its gluteal tendons carry extra compression all day, before activity even enters the picture. If the pelvis is being pulled crooked and nobody corrects it, you can strengthen and stimulate the tendon all you want — the extra load that irritated it is still there tomorrow.
2

Change the load — starting today

You leave the first visit knowing the compression story and exactly what to change: the sleeping setup (pillow between the knees; keep the top knee level with the hip), the sitting and standing habits, which exercises to stop (the cross-body stretches), and what your walking and stair volume should look like while the tendon calms.

None of this costs anything. All of it is load off the tendon, 24 hours a day. Skipping this step is why treatments fail — you cannot stimulate a tendon back to health while compressing it all night and hanging on it all day.

3

For the tendon that's stopped healing — restart it

If the exam says your tendon is past the stage where unloading alone will do it — and after years of symptoms, it usually is — this is where StemWave therapy comes in: focused acoustic waves delivered precisely to the affected tendon. Researchers call the mechanism mechanotransduction — cells respond to the dosed mechanical signal with increased local blood flow and renewed repair activity, the response the tissue stopped producing on its own. It's the wake-up call, not the whole recovery: the tendon still rebuilds the way tendons always rebuild — gradually, under progressively managed load.

1st

Candidates get a test treatment at the evaluation itself.

We find the spot by exam and by your feedback, treat it that day, and you feel what a session is like before committing to anything. Sessions are brief, needle-free, no downtime. A course runs five to ten visits depending on severity — chronic cases usually need the full ten — and you'll know the plan and the price before you start.

Rebuild the muscle — and re-level the pelvis

As the tendon desensitizes, we progressively strengthen the gluteals — pelvis-leveling work in positions that avoid compression — because a strong hip is what keeps this from coming back. And this is where the pelvic distortion findings from your exam get their treatment: while we're treating the tendinopathy itself at the greater trochanter, we're also working to balance the hip flexors and hamstrings and restore joint and fascial function in the low back — whatever was pulling the pelvis out of level.

The tendon gets the stimulus; the chain that overloaded it gets the correction. Then we release you. No year-long plans, no memberships. Boosters if you ever need them — the dental-checkup ethos, same as everything else we do.

What we won't do: quote you a success rate (this website never does), promise a timeline that ignores your stage, or treat a hip we haven't examined. Some people we examine, we refer elsewhere. That's part of the service.
06In his own words

"I just figured this was how it was going to be."

Years of the same hip pain. The same advice on repeat. Hear one patient describe what it's like to live with this condition for years — the sleep, the frustration, the treatments that kept wearing off — in his own words.

His experience is his own — every hip gets its own exam and its own answer.

07The next step

Find out what your hip is actually dealing with.

If the outside of your hip has been winning for months — or years — the next step isn't another round of rest and hope. It's an exam that names the real problem, stages it honestly, and gives you a straight answer: here's what this is, here's what will help, and here's what won't.

08Fair questions

Before you call.

Is it bursitis or tendinopathy — does it matter?

Here's the honest answer: with several tissues layered on top of each other, it's hard to tell exactly how much pain is coming from the bursa and how much from the tendons — and often both are involved. So we treat for the tendinopathy and expect the bursa to calm down along with it. Your own history is actually one of the best clues: rest, ice, and injections are bursitis treatments, so if you've already been down that road and the hip still hurts, you can be pretty confident there's a high tendon component. That's exactly the case where leveling the pelvis and treating the tendon with shockwave earns its place — taking the extra load off while stimulating the tendon's repair, so symptoms can settle as the tissue heals.

Why does it hurt most at night?

Side-lying compresses both hips at once — the bottom one against the mattress, the top one by dropping across midline. A firm pillow between knees and shins (keeping the top knee in line with the hip) is the single highest-value free change most people can make tonight.

Should I stretch it?

For this condition, no — cross-body and iliotibial-band stretches press the sore tendon against the bone and reliably aggravate it. The tight feeling is a symptom of compression, not a flexibility problem.

I already had a cortisone shot. Did it ruin anything?

One shot is not a catastrophe, and the relief window can even be useful. But the trials are clear that injections alone lose to load management over a year, and repeat injections raise concerns for tendon quality — so the shot should never be the whole plan.

Will I need an MRI?

Usually not — this is a clinical diagnosis, made with validated exam tests. Imaging earns its place when the story is atypical or the exam suggests a tear. If you already have imaging, bring it; we read it with you, in plain English.

How many visits will this take?

It depends on severity, but treatment courses run between five and ten sessions, sized to your case at the evaluation — and if the problem has been chronic, plan on the full ten. Then we do something that surprises people: we stop. We discontinue treatment and monitor the hip over the next three months, because tendon healing doesn't end when the sessions do — most patients continue to improve after the course is complete. The last visit isn't the finish line; it's where the tendon takes over. Booster treatments are sometimes needed down the road, case by case — but no open-ended plans, and you'll know the plan and price before you start.
