Can Hip Bursitis Cause Lower Back Pain?

Hip bursitis can absolutely produce or mimic lower back pain, and it does so frequently enough that researchers have spent decades trying to untangle the two conditions. In studies of patients already diagnosed with chronic low back pain, greater trochanteric pain syndrome (the updated term for what most people still call hip bursitis) has been found in anywhere from 18% to 45% of cases, depending on the population studied. The overlap between hip and spine symptoms is one of the more frustrating diagnostic puzzles in orthopedics, and the consequences of getting it wrong can include unnecessary imaging, failed treatments, and even unneeded surgery.

How Hip Pain Travels to the Lower Back

Your hip joint and lumbar spine are not separate systems. They share muscles, nerves, and a continuous chain of load-bearing structures. The gluteus medius and gluteus minimus muscles, which attach near the greater trochanter (the bony bump on the outer hip), also help stabilize the pelvis. When those structures are irritated or weakened, the pelvis tilts or shifts during movement, and the lumbar spine has to compensate. That compensation often shows up as low back pain, stiffness, or aching that feels like it originates in the spine even though the primary problem is at the hip.

The pain itself can radiate in confusing patterns. People with greater trochanteric pain syndrome typically experience pain that shoots down the outer thigh, sometimes with tingling or numbness in the leg. That pattern closely resembles sciatica, which is pain caused by a compressed nerve root in the lower spine. The similarity is so strong that one early study specifically described trochanteric bursitis as a condition that “simulates major hip diseases and low back pain” and “may also mimic nerve root pressure syndrome.”¹ The result is that many patients with hip bursitis end up being treated for a spine problem they don’t actually have.

It Might Not Actually Be Bursitis

One complication worth knowing about: the term “hip bursitis” is somewhat outdated. For years, doctors assumed that the trochanteric bursa (a fluid-filled sac that cushions the outer hip) was the main source of lateral hip pain. Imaging studies have since shown that the real culprit, more often than not, is damage to the gluteal tendons rather than inflammation of the bursa itself. MRI and ultrasound research has found that greater trochanteric pain syndrome is commonly caused by gluteus minimus or gluteus medius tendon injury rather than true bursitis.²

This distinction matters because the treatment for a torn or degenerating tendon is different from the treatment for an inflamed bursa. But for the question of whether the condition causes back pain, the mechanism is similar either way. Weakened or painful gluteal structures destabilize the pelvis and force the spine to pick up the slack. Whether the problem originates in the bursa or the tendon, the downstream effect on the lower back is the same.

How Common the Overlap Really Is

Studies looking at patients with chronic low back pain have consistently found high rates of concurrent hip pathology. One of the earlier investigations tested three groups of low back pain patients and identified greater trochanteric pain syndrome in 25%, 18%, and 45% of each group, with higher rates linked to female sex and longer duration of back symptoms.³ These aren’t rare coincidences. Among patients referred to spine clinics specifically for evaluation of degenerative lumbar conditions, greater trochanteric pain syndrome has been described as “very common but often unrecognized or misdiagnosed.”⁴

The connection also runs in the other direction. Research has found a significant positive correlation between sacroiliac joint dysfunction and hip pathology, meaning that in both athletes and non-athletes, people with more sacroiliac involvement also tend to have more severe hip problems.⁵ The hip and spine are so intertwined that clinicians now use the term “hip-spine syndrome” to describe patients who have degenerative disease in both areas simultaneously, with overlapping symptoms that can include low back pain, groin pain, radiating leg pain, and difficulty walking.⁶

The Misdiagnosis Problem

The overlap between hip bursitis symptoms and spine-related pain creates a real diagnostic trap, and it goes both ways. In a study of 657 patients referred for sciatica, roughly 11% turned out to have greater trochanteric bursitis rather than true sciatica. Another 2.7% had both conditions at the same time. The misdiagnosed patients were overwhelmingly women, with an average age around 60.⁷ That study’s authors bluntly warned that the misdiagnosis leads to “unnecessary imaging tests and treatment approaches, burdening both the patient and the health system.”

The reverse error also happens. A separate group of researchers documented 18 patients initially diagnosed with trochanteric bursitis that didn’t respond to treatment. The actual causes turned out to include lumbar nerve root irritation and lumbar facet syndrome with pain referred to the lateral thigh.⁸ In those cases, the spine was the source all along, and the outer hip pain was just the area where patients felt it most.

The practical takeaway is that if you’ve been told you have hip bursitis but your back also hurts, both could be contributing. And if you’ve been treated for a back problem without improvement, the hip should be examined carefully before assuming the spine diagnosis is correct.

Why Imaging Doesn’t Always Settle the Question

You might expect that an MRI would clear things up, but the picture is messier than that. In a study of completely pain-free people, about 36% of hips showed small areas of enhancement on MRI around the greater trochanter, and about 4% showed larger fusiform areas of enhancement.⁹ In other words, MRI can show what looks like pathology in hips that feel perfectly fine. A systematic review of imaging for greater trochanteric pain syndrome found that MRI had the strongest correlation with clinical and surgical findings, but also noted that false positives were common and the overall data was limited.¹⁰

This means a doctor can’t simply order an MRI of the hip and point to a finding as proof. The clinical exam, including pressing on the greater trochanter, testing hip abduction strength, and observing the patient’s gait, still plays a central role in figuring out what’s actually generating the pain. When both the hip and the spine look abnormal on imaging, the challenge becomes determining which one is the main pain driver and which one is an incidental finding.

Shared Risk Factors That Fuel Both Conditions

Part of the reason hip bursitis and low back pain so often appear together is that many of the same risk factors drive both conditions. Understanding these shared contributors can help you address the root of the problem rather than chasing symptoms in one area while ignoring the other.

• Leg length difference: Even a modest discrepancy in leg lengths tilts the pelvis, which strains the trochanteric bursa on one side and puts asymmetric load on the lumbar discs. Leg length inequality has been associated with low back pain, greater trochanteric bursitis, and degenerative hip disease simultaneously.¹¹
• Higher body weight: Elevated BMI has been identified as a risk factor for trochanteric bursitis, and excess weight also increases the compressive load on lumbar discs. One study found that higher BMI combined with lower bone quality had a supra-additive effect on bursitis risk, meaning the two factors together were worse than either one alone.¹²
• Weak hip muscles: Gluteal weakness is a known contributor to both greater trochanteric pain and lumbar instability. When the hip abductors can’t do their job, the pelvis drops during walking, and the lumbar spine compensates with lateral bending that stresses the facet joints and discs.
• Female sex: Women are significantly more represented among patients with greater trochanteric pain syndrome, likely due to wider pelvis anatomy that increases the angle of pull on the gluteal tendons. Women also have higher rates of chronic low back pain in general.

The fact that these risk factors overlap so heavily helps explain why treating only the hip or only the back often fails. If the underlying issue is pelvic instability from weak gluteal muscles and a few extra pounds, a cortisone injection into the trochanteric bursa may help temporarily but won’t fix the biomechanical pattern that keeps reloading both areas.

When Spine Surgery Creates Hip Bursitis

Here’s one connection that surprises most patients: spinal fusion surgery can actually trigger hip bursitis. Research looking at acute trochanteric bursitis after lumbosacral fusion found it to be a real complication, with higher BMI, lower vitamin D levels, and reduced bone quality all increasing the risk.¹² The mechanism makes intuitive sense: fusing segments of the lumbar spine changes how the pelvis moves and redistributes mechanical stress to the hip. A case report of hip-spine syndrome documented a patient who developed bilateral hip pain after multiple surgeries for a spinal deformity, requiring additional treatment to address the hip problems the spine surgery helped create.¹³

This doesn’t mean spinal fusion is a bad idea for patients who need it, but it does highlight the importance of evaluating the hip before and after spine procedures. If a patient already has borderline gluteal tendinopathy or a BMI that puts them at risk, the surgical team should be aware that the hip may become the next source of problems.

Why the Pain Can Become Self-Reinforcing

When hip bursitis and back pain coexist for weeks or months, the nervous system itself can start amplifying the problem. Chronic pain from any source can trigger a process in which the spinal cord and brain become increasingly sensitive to pain signals, responding more strongly to stimuli that wouldn’t normally hurt. This process involves immune cells in the spinal cord that release inflammatory molecules, which in turn make the nerve pathways more excitable.¹⁴ At that point, the pain is no longer purely about what’s happening in the hip or the back. The nervous system itself has changed.

Research on chronic low back pain has found that lower overall muscle strength, along with psychological factors like catastrophizing (expecting the worst), are associated with greater pain during movement.¹⁵ This is relevant because someone dealing with both hip and back pain is more likely to reduce their activity, lose muscle strength, and develop anxiety about movement, all of which feed into the sensitization cycle. Breaking that cycle often requires addressing the psychological and muscular dimensions alongside the structural ones.

What Actually Helps

Because the hip and the lower back are mechanically linked, the most effective treatment strategies address both areas rather than focusing on one in isolation. Hip-strengthening exercises, particularly for the gluteus medius and gluteus minimus, have been shown to reduce low back pain in patients with lumbar instability more effectively than conventional therapy alone.¹⁶ Exercises like side-lying hip abduction, clamshells, and single-leg bridges target the muscles that stabilize the pelvis and reduce the compensatory strain on the lumbar spine.

For the hip pain specifically, corticosteroid injections into the trochanteric bursa have been a standard treatment for decades, but the evidence on their long-term benefit is mixed. They tend to provide relief for a few weeks, sometimes longer, but the pain frequently returns. More recent research has examined platelet-rich plasma injections as an alternative. A systematic review found that multiple studies showed PRP injections outperforming corticosteroid injections for greater trochanteric pain syndrome, with benefits lasting up to two years compared to a maximum of about six months for corticosteroids.¹⁷ PRP is not universally covered by insurance, however, and the evidence base is still building.

Other conservative measures that tend to help include physical therapy focused on core and hip stability, modification of aggravating activities (sleeping on the affected side, prolonged standing, and crossing the legs are common triggers), weight management, and addressing any leg-length discrepancy with a shoe insert. If both a spine condition and a hip condition are identified, clinicians managing hip-spine syndrome have to decide which to treat first, and the answer usually depends on which one appears to be generating the more dominant symptoms.

Getting the Right Diagnosis

If you’re experiencing both hip and lower back pain, the single most useful thing you can do is make sure both areas get examined. A thorough clinical exam for greater trochanteric pain syndrome is straightforward. Tenderness when pressing on the bony prominence of the outer hip, pain with resisted hip abduction, and pain when lying on the affected side are the classic findings. The symptoms that set it apart from true sciatica include pain that’s worst over the outer hip rather than deep in the buttock, and pain that’s aggravated by specific positions like standing for a short time, going down stairs, or crossing your legs.³

If you’ve been diagnosed with a lumbar disc problem or sciatica but haven’t had a hands-on examination of the hip, it’s worth asking for one. The studies on misdiagnosis suggest that clinicians sometimes head straight for spinal imaging when lateral hip pain or thigh pain is present, missing a condition that can be identified with a few minutes of palpation and movement tests. Catching greater trochanteric pain syndrome early can spare you imaging you don’t need, injections or surgery that target the wrong structure, and months of pain that could have been addressed with a more focused rehabilitation program.
