What If a Cortisone Shot Doesn’t Work for Hip Bursitis?

A cortisone shot that fails to relieve hip bursitis pain is actually common, and it frequently points to a problem with the diagnosis rather than the treatment. Studies show symptom resolution after corticosteroid injection ranges anywhere from about half of patients to nearly all, depending on the study and what other therapies were combined with it. When you land on the low end of that range, the most productive question is usually not “should I get another shot?” but “is bursitis really what’s going on?” The answer reshapes everything that comes next.

The Diagnosis Itself May Be Wrong

The single most important reason a cortisone shot fails for “hip bursitis” is that true bursitis is rarer than most people realize. A study using ultrasound to examine patients diagnosed with greater trochanteric pain syndrome found that bursitis was present in only a minority. The actual cause was usually some combination of damage to the gluteus medius and gluteus minimus tendons and irritation of the iliotibial band running over the outside of the hip.¹ When you inject a steroid into a bursa that isn’t actually inflamed, you’re treating the wrong tissue.

This distinction matters because cortisone works by reducing inflammation. If the bursa is swollen and irritated, flooding it with a corticosteroid makes sense and often provides fast relief. But if the real problem is a fraying gluteal tendon or a tight iliotibial band grinding over bone, the anti-inflammatory effect may dampen pain temporarily without addressing the structural issue. That’s why many patients report initial improvement followed by a return of symptoms within weeks or a few months.

Patients with gluteal tendon problems typically describe a dull ache over the outside of the hip that worsens when lying on that side or climbing stairs. Because these symptoms overlap heavily with bursitis, misdiagnosis is routine. Patients are often initially told they have trochanteric bursitis, radiculopathy, or even osteoarthritis before the tendon damage is identified.²

Did the Needle Actually Hit the Right Spot?

Even when the diagnosis is correct, injection technique can determine whether you get relief. Most cortisone shots for hip bursitis are given using anatomical landmarks, meaning the clinician feels for the bony prominence on the side of your hip and estimates where to place the needle. This works reasonably well in the short term, but ultrasound-guided injections tend to deliver better results, at least initially.

A study comparing ultrasound-guided and landmark-guided trochanteric bursa injections found that pain scores were similar at two weeks, but by six months the ultrasound-guided group had significantly less pain. Both groups ended up needing their next intervention at roughly the same time, around eight to nine months out, suggesting the advantage of precision fades over time.³ A separate trial confirmed the pattern: ultrasound-guided injections provided more noticeable early improvements in pain during activity and overall hip function at one month, but the two approaches converged in the longer term.⁴

If your first injection was given by landmark only and it didn’t help much, it’s reasonable to ask whether an ultrasound-guided injection might be worth trying before moving on to other treatments. But if an image-guided injection also fails, the conversation needs to shift toward what else could be causing the pain.

Getting a Clearer Picture with Imaging

When a cortisone shot underperforms, imaging is the logical next step. MRI and ultrasound are both used to look for gluteal tendon tears, but their accuracy varies. A systematic review of the evidence found that MRI sensitivity ranged widely, from as low as a third of tears detected to all of them, with high specificity but frequent false positives. Ultrasound, when performed by a skilled practitioner, had sensitivity in the range of about 80 to 100 percent and a very high positive predictive value.⁵

The takeaway is that ultrasound in experienced hands may be the better tool for identifying tendon tears, though MRI is more commonly ordered in general practice. If you’ve had an MRI that looks “normal” but you’re still in pain, it’s worth knowing that MRI can miss partial tears, and a musculoskeletal ultrasound might catch what MRI didn’t. On the other hand, an MRI finding of tendon abnormality doesn’t automatically mean surgery. Many people have mild tendon changes on imaging that don’t fully explain their symptoms.

The Role of Your Spine

One overlooked factor when a cortisone shot doesn’t work is what’s happening in your lower back. A study of nearly 100 patients with greater trochanteric pain syndrome found a correlation between lumbar degenerative disease, gluteus medius tendon problems, and trochanteric bursitis. About 63 percent of patients responded to a combined local anesthetic and cortisone injection, but the major predictor of pain returning was moderate to severe lumbar spine degeneration.⁶

This makes intuitive sense. The nerves that supply sensation to the outer hip originate in the lumbar spine. If those nerves are being irritated by disc degeneration or spinal narrowing, a cortisone shot to the hip treats the symptom location rather than the pain source. For patients whose lateral hip pain keeps coming back despite apparently good injections, a closer look at the lumbar spine with imaging or a diagnostic nerve block may reveal the actual driver.

Shockwave Therapy

Extracorporeal shockwave therapy sends pressure waves through the skin into the painful area, and it has accumulated a solid track record for greater trochanteric pain syndrome. A systematic review found low-energy shockwave therapy to be superior to other nonoperative treatments for trochanteric pain.⁷ A randomized controlled trial comparing focused shockwave therapy to conventional ultrasound therapy found significantly greater pain reduction at both two and six months in the shockwave group.⁸

A more recent trial added another dimension. Researchers compared shockwave therapy and a structured exercise program, then crossed over patients who hadn’t responded to their first treatment. Patients who hadn’t improved after two months on one therapy recovered when switched to the other or given both, regardless of the sequence. That said, the shockwave-first group showed more pronounced functional gains.⁹ The practical lesson is that shockwave therapy is a legitimate next step if cortisone hasn’t worked, and combining it with targeted exercise may be more effective than either alone.

Access can be a hurdle. Not every orthopedic or sports medicine clinic offers shockwave therapy, and insurance coverage varies. A typical treatment course involves three to five sessions spaced a week apart. The procedure is uncomfortable during the pulses but doesn’t require anesthesia or downtime.

Platelet-Rich Plasma Injections

Platelet-rich plasma, or PRP, has gained attention as an alternative to cortisone for gluteal tendinopathy. A randomized, double-blind trial comparing a single PRP injection against a single cortisone injection found that both groups improved similarly in the first six weeks. By 12 weeks, the PRP group pulled ahead: about 82 percent of PRP patients achieved a meaningful improvement, compared with roughly 57 percent of the cortisone group.¹⁰

A systematic review that pooled additional studies echoed the finding. PRP injections provided superior clinical outcomes at 24 weeks compared to corticosteroid injections, and follow-up data suggested PRP benefits lasted up to two years, whereas cortisone relief peaked at around six weeks and faded by six months.¹¹ The catch is that PRP takes longer to kick in. You’re essentially trading a fast but short-lived cortisone benefit for a slower but more durable PRP response. PRP is also rarely covered by insurance, and a single injection can cost several hundred dollars out of pocket.

One nuance worth noting is that PRP appears most relevant when the underlying problem is tendon degeneration rather than pure bursitis. If true bursal inflammation is actually present, cortisone is still the more targeted option. PRP’s theoretical advantage lies in stimulating tissue repair rather than simply suppressing inflammation.

Why Repeating Cortisone Isn’t Always the Answer

When a first cortisone shot provides partial or short-lived relief, the temptation is to repeat it. Many clinicians will offer a second injection, and that can be reasonable, but a pattern of repeated injections has real downsides. A systematic review of adverse effects from extra-articular corticosteroid injections catalogued a range of complications including tendon rupture, skin thinning and discoloration at the injection site, and in rare cases, serious infections.¹² A separate review confirmed that local effects such as skin atrophy, hypopigmentation, and accelerated joint degeneration are recognized risks of repeated corticosteroid injections for musculoskeletal conditions.¹³

The concern specific to the greater trochanter area is the gluteal tendons. Cortisone can weaken tendon tissue over time, which is exactly the wrong effect if your pain is coming from a tendon that’s already degenerating. Most guidelines informally cap trochanteric cortisone injections at two or three per year, though there isn’t a universally agreed-upon limit. If you find yourself needing a third or fourth shot in the same year, that’s a signal to pursue other treatment options rather than continuing to suppress symptoms.

When Surgery Makes Sense

Surgery enters the conversation for patients who have failed multiple rounds of conservative treatment and have a clearly identified structural problem, typically a significant gluteal tendon tear or chronic iliotibial band friction that hasn’t responded to anything else. Surgical options include removing the inflamed bursa, releasing or reconstructing the iliotibial band, and repairing torn gluteal tendons. A systematic review found that all surgical techniques studied were superior to cortisone and physical therapy on pain and functional scores, though the specific approach varied based on the underlying pathology.⁷

That doesn’t mean everyone with persistent lateral hip pain should rush to the operating room. Surgery carries its own risks, recovery is measured in months, and outcomes depend heavily on patient selection. A person with a clear full-thickness gluteal tendon tear and six months of failed conservative management is a very different surgical candidate than someone with vague lateral hip pain and no obvious tear on imaging. Most surgeons want to see documented failure of at least two or three nonsurgical approaches before recommending an operation.

Central Sensitization and Chronic Pain

For some patients, greater trochanteric pain becomes self-perpetuating regardless of the original cause. Research has found evidence of central sensitization in people with this condition, meaning the nervous system amplifies pain signals beyond what the local tissue damage would explain. In one study of primary care patients with greater trochanteric pain syndrome, about a third showed altered pain processing patterns consistent with central sensitization, including reduced ability to dampen pain signals and heightened responses to repeated stimulation.¹⁴

When central sensitization has set in, no local injection will fully resolve the pain because the problem is partly in how the brain and spinal cord are processing signals. These patients often benefit from a broader approach that includes graded exercise, sleep optimization, and sometimes medications or therapies that target the nervous system directly. If you’ve tried cortisone, PRP, shockwave, and physical therapy and nothing is making a dent, central sensitization is worth discussing with your provider. It’s not a psychological diagnosis; it’s a neurological pattern that responds to different treatment strategies.

Metabolic and Systemic Factors That Undermine Tendons

The health of your tendons isn’t determined solely by what happens locally at the hip. A review of systemic influences on tendinopathy identified several pathways through which metabolic conditions degrade tendon tissue. Poorly controlled blood sugar leads to structural changes in the collagen that makes up tendons, making them stiffer and more vulnerable to damage. Abnormal cholesterol levels drive low-grade inflammation in and around tendons. Hormonal shifts, particularly declining estrogen levels, disrupt the normal turnover of tendon collagen. And the cellular aging process itself produces inflammatory signals that reduce a tendon’s ability to tolerate mechanical load.¹⁵

The review argued that traditional local treatments, including cortisone, have limited effectiveness precisely because they ignore these systemic contributors. If you have diabetes that isn’t well managed, or high cholesterol, or you’re going through menopause, your tendons are being weakened from the inside while you try to fix them from the outside. This doesn’t mean you shouldn’t pursue local treatments, but it does mean that addressing metabolic health, through diet, exercise, medication, or hormone management, may be just as important for resolving stubborn hip pain as anything your orthopedist does in the exam room. It’s the kind of connection that rarely comes up during a cortisone injection appointment but can make or break long-term recovery.
