"Hip bursitis" is one of the most over-used labels in hip pain — partly because outer-hip pain is common, and partly because several different problems all produce pain in roughly the same area. Getting the label wrong matters: it sends treatment in the wrong direction and is a common reason pain persists.
In fact, the single thing most often mistaken for hip bursitis is the condition that usually is the real diagnosis — gluteal tendinopathy. Here are the key conditions worth ruling in or out.
1. Gluteal tendinopathy (the usual real diagnosis)
Most "hip bursitis" is actually irritation of the gluteal tendons — gluteus medius and minimus — not an inflamed bursa. Both sit under the umbrella of greater trochanteric pain syndrome (GTPS). Same location as bursitis, but the treatment differs: gluteal tendinopathy responds to progressive loading and compression reduction, not anti-inflammatory approaches alone.
Tell-tale signs: pain worse lying on the affected side, worse with single-leg loading (stairs, walking on slopes), and often worse after sitting cross-legged or standing with all weight dumped to one side.

OA pain is usually felt in the groin and front of the hip, often radiating into the thigh. It typically brings morning stiffness that eases with movement, and reduced internal rotation (difficulty turning the leg outward). Pain tends to worsen with prolonged activity and settle with rest.
The outer bony point is not the primary location for hip OA — that's a useful quick differentiator from GTPS.
→ Hip osteoarthritis and replacement rehab →3. Hip impingement (FAI) or a labral tear
FAI and labral tears are intra-articular problems — the joint itself. Pain is typically deep in the groin, often described with the "C-sign" (patients cup the front of the hip with the thumb and fingers). You may feel catching, pinching or a sense of something getting stuck, particularly in deep hip flexion — squatting, sitting in low chairs, or bringing the knee toward the chest.
This is a different mechanism and a different region from outer-hip bursitis-type pain.
→ FAI and labral tears explained →4. Referred pain from the lower back
The lumbar spine can refer pain to the outer hip and buttock — and it can feel remarkably similar to GTPS. Clues that suggest a back origin: pain that spreads rather than staying local, pain that changes with back position (bending, sitting, rotating the spine), or the presence of nerve-type symptoms — pins and needles, numbness, or pain extending down the leg.
A physiotherapist who screens the lumbar spine will pick up on this where a generic hip assessment often won't.
→ Hip pain causes and the role of the spine →5. Less common: true bursitis, infection, and other causes
A genuinely inflamed bursa does occur — often after a direct knock to the outer hip — but is less common than the tendon-driven presentations above. Of the conditions that need prompt medical assessment, a hot, swollen, feverish hip is the key red flag: this can indicate infection in the joint (septic arthritis), which requires urgent treatment.
If the hip is hot to touch, you feel unwell, and there's fever alongside the pain, seek medical review — not physiotherapy — today.
Why misdiagnosis matters: Treating a gluteal tendon problem with rest and anti-inflammatories alone doesn't rebuild the tendon's capacity — so when you return to activity, the pain typically comes back. Getting the right structure identified means the treatment actually targets what's driving the problem.
Quick comparison
| Condition | Typical pain location | Key tell-tale signs |
|---|---|---|
| Gluteal tendinopathy | Outer bony point (greater trochanter) | Worse lying on it; worse with single-leg loading; stairs and slopes |
| Hip osteoarthritis | Groin / front of hip, often thigh | Stiffness after rest; reduced rotation; activity-related pain |
| FAI / labral tear | Deep groin | C-sign; catching in deep flexion; pinching with hip flexion |
| Back-referred pain | Outer hip, vague / spreading | Changes with back position; nerve symptoms; spreads |
Red flag: hot, swollen hip with fever
A hot, swollen, feverish hip needs urgent medical assessment today — not physiotherapy. This can indicate septic arthritis or another infection requiring prompt treatment.
When to see a specialist
If outer-hip pain isn't settling with "bursitis" treatment, it may be mislabelled — and mislabeling is one of the most common reasons hip pain becomes persistent. A specialist assessment identifies which structure is actually driving the pain and builds a targeted rehabilitation plan around it.
Consider a specialist assessment if your pain has lasted more than a few weeks, isn't responding to generic treatment, or keeps returning after initial improvement.

What is often misdiagnosed as hip bursitis?
Most commonly gluteal tendinopathy — the tendon problem that sits under the GTPS umbrella. But also hip osteoarthritis, FAI/labral tears, and referred pain from the lumbar spine.
How do I know if it's bursitis or something else?
Location and behaviour are the main clues. Outer bony point pain that's worse lying on it and with single-leg loading tends toward gluteal tendinopathy. Deep groin pain with catching points toward FAI or labral tear. Pain that changes with back position or spreads suggests referred pain from the lumbar spine.
Can a hip scan tell the difference?
Imaging helps, but findings must be interpreted alongside clinical examination — incidental findings are common and don't always correlate with symptoms. An experienced clinician uses both together.
Why does misdiagnosis of hip bursitis matter?
Because the treatment for the wrong condition often doesn't work — and can make things worse. Treating a gluteal tendon problem with generic anti-inflammatories or rest alone doesn't rebuild capacity, so the pain returns.
What does a hot, swollen hip mean?
A hot, swollen, feverish hip needs prompt medical assessment to exclude infection. This is a red flag that sits outside routine musculoskeletal causes.
