Everything you were told to stretch is what is compressing it.

PRP FOR GLUTEAL TENDINOPATHY

Pain on the outside of the hip that makes lying on that side impossible is almost never the hip joint. It is the gluteal tendons. It is one of the most often misdiagnosed problems in muscle and joint medicine.

Is outer hip pain bursitis or gluteal tendinopathy?

“Trochanteric bursitis” was the standard label. The standard treatment was a steroid injection into the bursa (a small fluid sac). Then imaging and surgical studies showed the main problem is something else. It is tendinopathy of the gluteus medius and minimus where they attach to the greater trochanter (the bony point of the hip). Bursa inflammation was secondary or absent.

The name matters because it drove treatment. Injecting steroid into a bursa to treat a degenerate tendon relieves symptoms for a couple of months. It also weakens the tendon. In this spot, where the tendons are already failing, that is a poor trade. The current term is greater trochanteric pain syndrome. The underlying problem is a tendon.

What makes gluteal tendinopathy worse?

Gluteal tendons fail under compression (squeezing) more than under tension (pulling). The iliotibial band runs right over them. Anything that adducts the hip, bringing the knee toward the midline, presses the band into the tendon and where it attaches.

That single mechanism explains the whole symptom pattern. It also explains what to stop doing:

• Lying on the affected side squeezes it directly. That is why night pain dominates.
• Lying on the good side lets the painful leg drop across the midline, which squeezes it too. A pillow between the knees fixes this.
• Standing hanging on one hip, the classic waiting posture, adducts and squeezes.
• Crossing the legs, deep stretching of the ITB, and downhill walking all do the same.
• Stretching the outside of the hip, the gut response, reliably makes it worse. It is the most common self-inflicted error.

Who gets gluteal tendinopathy, and why is it mostly women?

This is overwhelmingly a condition of women around and after menopause. That pattern is a clue, not a coincidence. Estrogen affects how tendons build collagen and how stiff they are. The gluteal tendons sit where falling estrogen and rising compression arrive at about the same stage of life.

That idea has actually been tested. A 2 × 2 factorial randomized trial enrolled 132 postmenopausal women with greater trochanteric pain syndrome. It randomized them to menopausal hormone therapy or placebo cream. It also randomized them to tendon-specific or sham exercise. Every group also got education on avoiding gluteal tendon compression and managing load. Three findings, all useful:

• Everybody improved, at 12 weeks and still at 52 weeks, in every arm.
• Targeted exercise did not beat sham exercise on any outcome. What all four groups shared was the education about compression and load. That is the strongest available argument that the compression message on this page is the active ingredient, not the specific exercises.
• Hormone therapy did beat placebo — but only in the women with a BMI under 25. In them, the difference on the gluteal tendinopathy score reached 20.7 points at 12 weeks (95% CI 10.2 to 31.2). It still measured 16.7 points at 52. There was a significant interaction between the cream and BMI.

That last result is why this page exists in the form it does. One terrain variable's effect was gated by another terrain variable. Hormonal status mattered, but only where the metabolic picture let it. It is the clearest example on this site that these factors are not a checklist to tick off one by one. They interact, and the interaction is where the result lives. What we measure is on the metabolic health page.

Two limits on that. Hormone therapy is a decision for you and the physician who manages it. It is made on the whole picture, not on a tendon. Nothing here is a recommendation to start it. And this was one trial in postmenopausal women. It does not describe men or younger women with the same diagnosis.

Does PRP work for gluteal tendinopathy?

A reasonable use, and one where the comparison against corticosteroid has been studied directly. A randomized trial of gluteal tendinopathy found PRP superior to corticosteroid at twelve weeks. The advantage held at two years. That is one of the cleaner results in the regenerative research.

That fits the biology. A degenerate tendon does not need suppression. And steroid injected around already-weakened gluteal tendons has been associated with progression to tearing.

What else it might be

• Hip osteoarthritis — groin pain and lost internal rotation, not lateral tenderness
• Lumbar referral — L4–L5 pathology referring laterally, with a normal local examination
• Gluteal tendon tear — marked weakness and a positive Trendelenburg sign, which changes management
• Sacroiliac pain — posterior rather than lateral

The loading program

Load management first, then strengthening. Removing compression stops the tendon getting worse. Abductor (outer hip muscle) strength stops it coming back.

• Weeks 0–2 Compression removed: pillow between the knees, no crossed legs, no ITB stretching, no hanging on one hip. Isometric abduction holds.
• Weeks 2–8 Building abduction strength in neutral, avoiding positions that adduct the hip. Side-lying work is added carefully, because the position itself compresses.
• Weeks 8–16 Loaded single-leg work, step-ups, and gait retraining to stop the pelvis dropping.
• Ongoing Keep abductor strength up for good. This tendon comes back in people who stop.

What has to be true for this to hold

The compression idea above is not background. It decides who this works for. A tendon squeezed for eight hours a day will keep failing no matter what is injected into it. So the honest entry requirement here is about behavior as much as anatomy.

The person this suits has had lateral (outer) hip pain for more than three months. They are tender over the greater trochanter and cannot lie on that side at night. No findings point into the joint itself. A steroid injection that helped for a few weeks and then wore off fits the picture; it does not argue against it. And this is the part that decides it: they are willing to change how they sit, stand and sleep. That is because crossed legs, standing with the hip dropped, and side-lying without a pillow between the knees keep loading the tendon against the bone.

It does not suit a full-thickness gluteal tendon tear with real weakness. That is a structural problem. It does not suit hip arthritis showing up as groin pain, which is treated as hip osteoarthritis. It does not suit referred pain from an untreated lower spine. That is why telling the hip from the back comes first. And it does not suit anyone unwilling to address the compression, because the tendon does not care what was injected if the load never changes.

Why it is so often missed

Three things send this diagnosis wrong. Together they account for years of needless treatment in a lot of people.

The scan finds something else. A hip X-ray in a fifty-five-year-old often shows some degenerative change. Once a report mentions arthritis, the lateral (outer) hip pain gets blamed on it. The two often exist together, and the tendon is usually what hurts.

The word bursitis persists. It is still widely used. It still prompts steroid shots into the bursa. And it still frames the problem as inflammation to be suppressed, not a tendon to be rebuilt.

The advice is backward. Patients are often told to stretch the iliotibial band and foam-roll the outside of the hip. Both squeeze the tendons against the trochanter. That is exactly the mechanism causing the problem. People who follow that advice faithfully get worse and decide they are doing it wrong.

What is the most effective treatment for gluteal tendinopathy?

• Remove compression. Free, immediate, and the single highest-yield step. Sleeping position, standing habits, leg crossing, and stopping the stretching.
• Load the abductors. Isometrics first for pain relief, then steadily building strength. This is the treatment that changes the path.
• Address the drivers above it. Gait, pelvic control, and the loss of fitness that started the loop.
• Then consider injection, where three months of the above has not been enough. Use PRP, not corticosteroid, for the reasons above.
• Shockwave therapy as a further option with its own evidence base.
• Surgical repair reserved for genuine full-thickness tears with weakness.

An injection offered before the first three have been tried is offered too early. The compression that nobody removed will undo it.

What people ask when they cannot lie on that side

Is this bursitis?

Usually not. It is tendinopathy, and the difference changes the treatment. What we treat.

Why does stretching make it worse?

Stretching the ITB compresses the tendons underneath it. It is the most common self-inflicted mistake. What to expect.

Should I have a cortisone injection?

PRP outperformed corticosteroid at two years in a randomized comparison here. The comparison.

Is my hip joint the problem?

If the pain is in your groin and rotation is limited, possibly. Lateral (outer) hip pain is usually tendon. PRP for hip osteoarthritis.

Will my gluteal tendinopathy ever go away?

It usually improves. In a trial of 132 postmenopausal women with this condition, every group was better at 12 weeks and still better at 52 weeks. What all of them shared was advice on avoiding compression and managing load. The catch is that this tendon comes back in people who stop. So abductor strength has to be kept up for good, not just until the pain fades.

How should I sleep with gluteal tendinopathy?

Stay off the painful side, because lying on it presses directly on the tendon, which is why night pain is so common. Lying on the good side can hurt too, because the painful leg drops across the midline and compresses the tendon anyway. A pillow between the knees fixes that. It costs nothing, and removing compression is the single highest-yield step.

How long should I try exercise before a PRP injection?

About three months. The order that works is to remove compression first. Then load the abductor muscles. Then fix gait and pelvic control. If three months of that has not been enough, an injection is reasonable, and PRP rather than cortisone. An injection offered before those steps is offered too early, because the compression nobody removed will undo it.

What if the gluteal tendon is torn?

A partial tear follows the same plan as tendinopathy: compression removed, the abductors loaded, then PRP where three months of that has not been enough. Marked weakness and a positive Trendelenburg sign change the plan, because a genuine full-thickness tear with real weakness is a structural problem, and surgical repair is kept for it. The exam sorts this out before anything is injected.
