Can Hip Bursitis Cause Groin Pain?

Hip bursitis can cause groin pain, but whether it does depends largely on which bursa is inflamed. The hip joint has several bursae, and the one most directly linked to groin pain is the iliopsoas bursa, which sits at the front of the hip near the crease of the groin. The more commonly diagnosed type, greater trochanteric bursitis, usually produces pain on the outer hip rather than in the groin. This distinction matters because people who feel groin pain and hear the phrase “hip bursitis” may assume the wrong structure is involved, leading to confusion about diagnosis and treatment.

The Hip Has More Than One Bursa

A bursa is a small, fluid-filled sac that reduces friction between bones, tendons, and muscles. The hip region contains at least a dozen of them, but three get most of the clinical attention. The trochanteric bursa sits over the bony prominence on the outer side of the thigh (the greater trochanter). The iliopsoas bursa lies deep in the front of the hip, between the iliopsoas muscle and the hip joint capsule. And the ischial bursa cushions the sit bone at the bottom of the pelvis. When people or doctors say “hip bursitis” without specifying which bursa, they usually mean trochanteric bursitis, because it is by far the most frequently diagnosed. But the location of pain differs dramatically depending on which sac is irritated.

Iliopsoas Bursitis and the Groin

The iliopsoas bursa is the largest bursa in the body and communicates directly with the hip joint in a substantial percentage of adults. When it becomes inflamed or distended, it presses on structures at the front of the hip, producing a deep, aching pain in the groin. This pain often worsens when you bring your knee toward your chest, walk uphill, or rise from a seated position. Iliopsoas bursitis is recognized as a well-established cause of groin pain, and it can become considerably more complex when the swollen bursa compresses nearby nerves or blood vessels.¹ In rare cases, the inflamed bursa can grow large enough to compress the femoral nerve, causing numbness or weakness in the thigh on top of the groin pain.

This type of bursitis sometimes develops after a total hip replacement, where implant components irritate the iliopsoas tendon. But it also occurs in people who have never had surgery, particularly runners, dancers, and anyone who repeatedly flexes the hip against resistance. The groin pain it produces can be remarkably similar to the pain from a labral tear, a hip flexor strain, or even a sports hernia, which is one reason it frequently goes unrecognized for months.

Greater Trochanteric Bursitis Typically Hurts the Outer Hip

Greater trochanteric pain syndrome, which encompasses trochanteric bursitis along with tendon problems in the surrounding gluteal muscles, is the form of hip bursitis most people encounter. Its hallmark symptom is tenderness on the outer part of the hip, often noticeable when lying on the affected side at night. The pain usually radiates down the outer thigh rather than into the groin.

That said, referred pain from the trochanteric region can occasionally extend toward the front of the hip and into the groin area. Pain referral patterns around the hip are notoriously variable. When researchers tested college athletes using a clinical provocative maneuver for hip impingement, about 60% of those with a positive test reported the pain in the groin, while roughly 38% felt it on the lateral hip.² That study was looking at impingement rather than bursitis specifically, but it illustrates how structures around the hip can produce pain in locations that don’t obviously match the anatomy. A person with trochanteric bursitis who also has altered gait mechanics or underlying joint changes might experience pain that creeps toward the groin, even though the primary source is on the outside of the hip.

Why Groin Pain Gets Blamed on the Wrong Structure

The groin is a crossroads. Hip joint problems, muscle strains, hernias, nerve entrapments, and referred pain from the lower back all converge in the same small area. When someone develops groin pain and has an imaging finding of hip bursitis, it can be tempting to connect the two, but the bursitis may be incidental and the real culprit may be something else entirely.

The hip joint itself is a common source of groin pain. Osteoarthritis of the hip, labral tears, and femoroacetabular impingement all tend to produce groin-dominant pain, and they can coexist with bursitis. In people with rheumatoid arthritis, for instance, trochanteric bursitis was found in 15 out of 100 consecutive patients in one study, and the researchers concluded it was an underdiagnosed and easily treatable cause of hip pain in that population.³ The point is that inflammatory joint disease can produce bursitis alongside other hip pathology, and sorting out which structure is generating which pain requires a careful examination rather than a guess based on imaging alone.

Adductor strains (groin pulls), osteitis pubis, and sports hernias are other common causes of groin pain that get confused with hip bursitis. Each has its own tenderness pattern and aggravating movements, which is why a clinician who presses on specific landmarks and tests range of motion can often narrow the diagnosis before any scan is ordered.

How Doctors Sort It Out

A physical exam is the first step. Iliopsoas bursitis tends to produce pain when the hip is flexed and externally rotated, and sometimes with resisted hip flexion. Trochanteric bursitis produces point tenderness directly over the greater trochanter and pain with resisted hip abduction. If pressing firmly on the outer hip reproduces your pain exactly, the problem is probably trochanteric. If the pain lives deep in the groin and gets worse when you pull your knee to your chest, the iliopsoas bursa or the hip joint itself is more likely involved.

When the exam isn’t conclusive, imaging fills the gap. Ultrasound can show fluid collection in a bursa and is especially useful because it can guide a diagnostic injection at the same time: if numbing the specific bursa abolishes the pain, you’ve confirmed which structure was responsible. MRI and CT provide more detailed views. MRI in particular can evaluate whether the bursa contains septa or synovial thickening and can assess surrounding tendons and the hip joint for concurrent problems.⁴ The imaging choice usually comes down to clinical suspicion and what the doctor needs to rule out.

Treatment When Bursitis Is the Confirmed Cause

Regardless of which bursa is involved, conservative treatment is the starting point and resolves most cases. Rest, activity modification, physical therapy to address biomechanical contributors, anti-inflammatory medication, and sometimes corticosteroid injections form the standard first line.⁵ For greater trochanteric pain syndrome, strengthening the gluteal muscles is considered a cornerstone because weakness in those muscles is often what caused the bursa to become irritated in the first place. For iliopsoas bursitis, stretching and strengthening the hip flexors, combined with temporarily avoiding the provocative activity, is usually enough.

Ultrasound-guided corticosteroid injections can provide meaningful relief when conservative measures stall. In a retrospective study of 137 patients with greater trochanteric pain syndrome who received ultrasound-guided trochanteric bursa injections, about 80% achieved successful outcomes at one month, roughly 65% at three months, and around 56% at six months.⁶ The decline over time suggests that injections work best as a bridge while rehabilitation addresses the underlying mechanical issue. Relying on injections alone without changing the movement pattern that started the problem tends to produce recurring flare-ups.

Platelet-Rich Plasma

For people who don’t respond to standard conservative care, platelet-rich plasma (PRP) injections have gained attention as an alternative. A systematic review found that PRP appears to be a promising, safe, and effective option for greater trochanteric pain syndrome that persists despite conventional treatment, with evidence of sustained symptom relief over time.⁷ PRP is not yet considered standard first-line treatment, and insurance coverage varies, but it fills a gap for patients stuck between failed injections and surgery.

Surgery as a Last Resort

A small subset of patients continue to have symptoms despite months of conservative management and injections. For persistent trochanteric bursitis, endoscopic bursectomy, where the inflamed bursa is removed arthroscopically, is an established surgical option.⁵ For iliopsoas bursitis, surgery sometimes involves releasing the iliopsoas tendon, particularly in post-hip-replacement cases where the tendon is being irritated by the implant. These procedures are uncommon because most bursitis resolves without them, but knowing they exist can be reassuring if you’ve been dealing with the problem for a long time.

The Rheumatoid Arthritis Connection

People with rheumatoid arthritis deserve a special mention because they develop trochanteric bursitis at higher rates than the general population, and the bursitis often goes undiagnosed. When researchers specifically examined 100 consecutive RA patients for trochanteric bursitis, they found it in 15% and concluded it was an easily treatable condition that clinicians should routinely screen for in anyone with RA and hip pain.³ The systemic inflammation of RA can inflame bursae throughout the body, and because RA also attacks the hip joint directly, patients and doctors alike tend to attribute all hip-region pain to the joint disease. A targeted examination of the trochanteric area can reveal a bursitis that responds to a simple local injection, sparing the patient from unnecessary escalation of their systemic medications.

Other inflammatory conditions, including gout, psoriatic arthritis, and ankylosing spondylitis, can similarly predispose people to bursitis. If you have a known inflammatory condition and develop new groin or hip pain, it’s worth asking your rheumatologist whether a bursitis evaluation makes sense alongside imaging of the joint itself.

Biomechanical Factors That Raise Your Risk

Bursitis around the hip doesn’t usually appear out of nowhere. Several biomechanical patterns make it more likely. A wider pelvis, leg-length discrepancy, tight iliotibial band, and weak hip abductors are commonly cited contributors to trochanteric bursitis. For iliopsoas bursitis, prolonged sitting with the hips flexed, sudden increases in running mileage, and repetitive kicking or dancing motions are frequent triggers.

Gait abnormalities play an underappreciated role. If you favor one leg because of knee pain, low back pain, or a foot problem, the altered walking pattern can overload the bursae on the opposite hip. This is why bursitis sometimes develops in a hip that seems structurally fine: the real problem is a mechanical compensation happening elsewhere in the kinetic chain. Physical therapists who evaluate gait and hip strength can identify these patterns and design a program to correct them, which tends to produce longer-lasting results than simply treating the inflamed bursa.

When Groin Pain Needs Urgent Attention

Most groin pain from bursitis is a nuisance, not an emergency. But certain features suggest something more serious. A femoral hernia can present as groin pain and, if it becomes incarcerated, requires immediate surgical repair. Hip joint infection (septic arthritis) causes severe groin pain with fever and an inability to bear weight; that’s also a medical emergency. Stress fractures of the femoral neck produce groin pain that worsens with impact activities and can progress to a complete fracture if ignored.

If your groin pain came on suddenly after a fall or trauma, is accompanied by a fever, or makes it impossible to put weight on the leg, those are reasons to seek same-day evaluation. Bursitis comes on gradually, fluctuates with activity, and allows you to walk even if walking is uncomfortable. Pain that breaks those rules warrants investigation beyond bursitis.

It’s also worth noting that referred pain from the lumbar spine can mimic hip and groin bursitis almost perfectly. A disc herniation or nerve root irritation at certain spinal levels sends pain straight into the groin and anterior thigh. If targeted treatment of the hip bursa doesn’t help, a look at the lower back is often the next productive step.
