Hip Pain: When Your Hip Hurts, It May Not Be Your Hip

You have pain in the area of your hip. Maybe your primary care physician told you it was hip bursitis. Maybe you've been stretching your IT band for six months without much to show for it. Maybe you had an X-ray that showed some arthritis and figured that explained everything.

It might. But it might not.

The hip region is one of the most diagnostically complex areas in the body — not because the structures are hard to understand, but because so many different structures can produce pain in exactly the same location. The lower back, the sacroiliac joint, the hip joint itself, the bursa, the tendons, and the nerves surrounding the joint can each generate symptoms that feel identical from the outside. And they frequently overlap.

Treating the wrong source will not resolve the problem. Accurate diagnosis is not a formality before treatment. It is the treatment.

Why Hip Pain Is So Easy to Misread

To understand why hip pain gets misattributed so often, it helps to understand what's actually in that region — and how different each structure's pain signature is.

The hip joint itself sits deep in the pelvis. True hip joint pain — from osteoarthritis, labral tears, or other joint pathology — is typically felt in the groin and front of the thigh. It worsens with weight-bearing and hip rotation. Patients often struggle to get in and out of a car, cross their legs, or put on shoes.

The area most people point to when they say "my hip hurts" — the outer prominence of the upper thigh — is not the hip joint at all. It's the greater trochanter, where several tendons and a bursa are located. Pain here has entirely different causes than groin pain, and a different treatment approach.

Meanwhile, the lower back and sacroiliac joint can refer pain into any part of the hip, buttock, or thigh — sometimes mimicking hip joint pain, sometimes mimicking outer hip pain, sometimes producing a diffuse aching the patient can't quite place.

Getting these sources right before starting treatment isn't optional. It's the only path to getting better.

The Bursitis Question

Greater trochanteric bursitis is one of the most common diagnoses patients bring to us after seeing their primary care physician. It's also one of the most commonly over-applied labels in orthopedics.

The bursa is a small fluid-filled sac that cushions the outer hip bone. When it's genuinely inflamed, it produces localized tenderness directly over that spot, pain when lying on the affected side, and aggravation with repetitive hip movement. These symptoms are real and they do occur.

But the exact same symptom profile is produced by gluteal tendinopathy — wear and partial tearing of the gluteus medius and minimus tendons that attach to the same area. These two conditions require completely different treatment. Injecting a bursa when the real problem is a degenerating tendon helps temporarily at best. Repeating that injection over time can actually make the tendon worse.

A large portion of what has historically been called hip bursitis is now understood to be a tendon problem — specifically, degeneration of those gluteal tendons, with secondary bursal irritation. The clinical distinction is clearly visible on diagnostic ultrasound. It is not visible on an X-ray.

This is not a criticism of primary care physicians, who are managing a very broad diagnostic scope. It is an argument for subspecialty evaluation when the pain persists, doesn't respond as expected, or doesn't have a clear pattern.

When the Hip Pain Is Actually Coming From Your Back

The nerve roots in your lower back supply sensation and motor function to the hip, thigh, and leg. When these nerves are compressed or irritated — by a disc herniation, spinal degeneration, or narrowing of the spinal canal — they can generate pain, numbness, tingling, or a sensation of muscular tightness anywhere along their path. That includes the outer hip, the buttock, the groin, and the knee.

Nerve-referred pain mimicking hip pathology is far more common than most patients realize. The clinical picture gets complicated quickly when a patient has both lumbar degeneration visible on imaging and hip findings — and the question becomes which one is actually generating the symptoms.

What the pattern looks like

Pain that changes with spinal position — sitting, bending forward, standing upright — is a strong signal that the spine is involved. True hip joint pain doesn't tend to behave that way. Numbness, tingling, or a change in strength in the leg or foot alongside the hip pain points to nerve involvement, which requires a different evaluation entirely.

These distinctions require a hands-on examination to identify. They cannot be diagnosed from an X-ray of the hip alone, and they will not resolve with hip-focused physical therapy or hip injections.

The Sacroiliac Joint

The sacroiliac joint connects the base of the spine to the pelvis. When it's inflamed or strained, it refers pain directly into the buttock and posterior hip — right where patients point when they say their hip hurts.

An X-ray or MRI of the hip joint won't show it. Sacroiliac pain is typically provoked by specific movements: rolling over in bed, getting up from a chair, single-leg activities. Patients often describe a sharp catch at the base of the spine that radiates into the buttock.

Same neighborhood as the hip. Not the hip.

What About Hip Arthritis?

Hip osteoarthritis is common, particularly in adults over 50, and it's a legitimate source of pain and functional limitation. But the presence of arthritis on imaging doesn't necessarily mean arthritis is the primary driver of a patient's symptoms.

The degree of arthritis visible on an X-ray doesn't reliably correlate with how much pain a person has. Some patients with significant arthritis have minimal symptoms. Others with moderate imaging findings have considerable difficulty. The imaging tells us about the anatomy. It doesn't tell us about the pain.

For patients with confirmed hip arthritis, the question worth asking is whether all of their symptoms are accounted for by the arthritis — or whether the lower back, the sacroiliac joint, or soft tissue sources are contributing to part of what they feel. Patients who undergo hip replacement and find some symptoms persist often discover in retrospect that they had a mixed picture, and the non-hip component wasn't identified beforehand.

That's not an argument against hip replacement when it's genuinely indicated. It's an argument for a thorough diagnostic evaluation before any major intervention.

When It's More Than One Thing

It's common — not unusual — for more than one source to be contributing to hip pain at the same time. Lower back degeneration and hip arthritis frequently coexist in the same age group. Sacroiliac dysfunction and outer hip tendinopathy can occur together.

Mixed presentations are challenging because treating one source often provides partial relief — which patients and clinicians sometimes interpret as confirmation that the right source was identified. When in fact it was one of two or three contributors.

Complete resolution requires identifying and addressing everything that's contributing. That's what a comprehensive evaluation is designed to do.

This is one reason patients who've been through multiple rounds of treatment without full resolution often benefit from a systematic re-evaluation — rather than another round of the same approach.

How We Approach Hip Pain at SOAR

When a patient comes to us with hip pain, our evaluation is designed to identify the source precisely before any treatment decision is made. Not just the area that hurts — all the structures that could be contributing.

Physical examination

A detailed history and hands-on exam — including specific tests for the hip joint, sacroiliac joint, lower back, and peripheral nerves — builds the diagnostic picture before we've ordered a single test. How the pain behaves with different positions and movements tells us a great deal.

Electrodiagnostic testing

When nerve involvement is suspected, EMG and nerve conduction testing give us objective information about nerve function that imaging can't provide. Which nerve is involved, at what level, and to what degree. Particularly useful when a patient's symptoms don't match their imaging, or when multiple potential sources are present.

Diagnostic ultrasound

Real-time ultrasound lets us visualize the bursa and tendons directly during the examination. We can identify tendinopathy, assess the bursa, and guide any injection to the precise structure involved — rather than approximating by feel. An injection placed under ultrasound guidance reaches its target at a significantly higher rate than one performed without imaging.

Treatment matched to the diagnosis

Once the source is identified, treatment follows. That may include targeted injections at the specific structure involved, a structured exercise program to address mechanical contributors, regenerative options for tendinopathy or cartilage degeneration, or further evaluation if additional sources emerge.

The goal is not to make the pain manageable. The goal is to find out what's causing it.

Signs Your Hip Pain Deserves a Second Look

Consider a formal evaluation if any of the following apply:

• Your pain changes depending on whether you're sitting, standing, or how your back is positioned
• You have numbness, tingling, or weakness in the leg or foot alongside the hip pain
• Pain radiates below the knee or into the groin
• A cortisone injection helped briefly, then stopped working
• Your diagnosis was made without a physical exam that also evaluated the lower back and sacroiliac joint
• You've been told it's bursitis but standard treatment hasn't resolved it
• You've been managing this for more than 6–8 weeks without meaningful improvement

If your hip pain was labeled without a comprehensive evaluation, it's worth asking whether the diagnosis is complete.

If you've been managing hip pain that isn't resolving as expected, we'd like to help you understand why. The most important question isn't where it hurts. It's what's causing it.
