Hip pain is not always coming from the hip joint itself. Pain in the groin, outer hip, buttock, or thigh can arise from arthritis inside the joint, irritated tendons and bursae around the hip, or a nerve problem that begins in the lower back.
That overlap is why two people who both say, “My hip hurts,” may need very different treatment plans.
Key takeaway: The location and behavior of your pain provide useful clues, but they do not replace an examination. Hip arthritis, lateral hip bursitis, and back-related pain can occur together, and the best treatment starts with identifying which structure is actually causing the symptoms.
A quick comparison
| Pattern | Hip arthritis | Lateral hip bursitis or greater trochanteric pain syndrome | Back-related pain |
|---|---|---|---|
| Most common location | Groin, front of the hip, or front of the thigh | Outside of the hip over the bony prominence | Low back, buttock, back or side of the thigh, sometimes below the knee |
| Common aggravating activities | First steps, prolonged walking, getting into a car, putting on shoes and socks | Lying on that side, stairs, hills, prolonged standing, crossing the legs | Sitting, bending, coughing, prolonged standing, or certain spine positions |
| Typical sensation | Deep ache, stiffness, catching, reduced motion | Tender, aching, burning, or sharp pain over the outer hip | Shooting, electric, burning, tingling, numbness, or weakness |
| Examination clue | Hip rotation is limited or painful | Direct tenderness over the greater trochanter and pain with resisted hip abduction | Nerve tension signs, sensory changes, reflex changes, or weakness |
| Common first imaging | Standing pelvis and hip X-rays | X-rays if needed; ultrasound or MRI for selected tendon problems | Spine imaging only when the history, examination, duration, or red flags support it |
Hip arthritis usually causes groin pain and stiffness
The hip is a ball-and-socket joint. Osteoarthritis develops when the smooth cartilage covering the ball and socket becomes damaged and the joint no longer moves as freely.
Patients often point to the groin when the hip joint is the main pain source. The pain may also travel into the front of the thigh or toward the knee. Some people feel buttock pain, but isolated outer-hip tenderness is less typical of arthritis.
Common clues include:
- Stiffness after sitting or when first getting up
- Difficulty putting on shoes or socks
- Trouble getting into or out of a car
- Reduced walking tolerance
- Pain when turning, pivoting, or changing direction
- Loss of hip rotation
- A limp that becomes more noticeable as symptoms increase
- Deep catching or grinding, although many arthritic hips do not make noise
Hip arthritis does not always hurt in proportion to what an X-ray shows. Some patients have substantial X-ray changes with manageable symptoms, while others have significant pain before the arthritis appears advanced. Treatment should be based on the whole picture, not the X-ray alone.
“Hip bursitis” often involves the gluteal tendons too
Pain over the outside of the hip is commonly called trochanteric bursitis. A more complete term is greater trochanteric pain syndrome, because irritation or degeneration of the gluteus medius and gluteus minimus tendons may be just as important as inflammation of the bursa.
The bursa is a thin, fluid-filled sac that helps reduce friction near the greater trochanter, the bony prominence on the outside of the upper thigh bone. The gluteal tendons attach in the same region.
Typical clues include:
- Pain directly over the outside of the hip
- Tenderness when you press on the bony area
- Pain when lying on the affected side
- Discomfort with stairs, hills, or prolonged walking
- Pain after standing with most of your weight on one leg
- Symptoms when crossing the legs or allowing the painful knee to fall inward
- Weakness or fatigue of the hip abductor muscles
- Pain that may travel down the outside of the thigh, usually not all the way into the foot
Many patients are surprised to learn that this problem is outside the hip joint. A hip replacement does not directly treat an isolated gluteal tendon or bursal problem, and an injection into the bursa will not correct arthritis inside the joint. Getting the location right matters.
Back-related pain can feel like hip pain
Nerves from the lower back travel through the buttock and leg. When a nerve root is irritated or compressed, pain may be felt in the hip region even when the hip joint itself is not the primary problem.
Back-related pain may come from a disc problem, spinal stenosis, arthritis of the lumbar spine, or another condition affecting the nerves.
Clues that suggest a spinal or nerve source include:
- Pain that starts in the back or buttock and travels down the leg
- Burning, electric, or shooting pain
- Tingling or numbness
- Symptoms below the knee
- Leg weakness, foot weakness, or a feeling that the leg may give way
- Pain that changes noticeably with sitting, bending, or arching the back
- Symptoms with coughing or sneezing
- Relief when leaning forward, particularly with some forms of spinal stenosis
Not every case of back-related hip pain includes low-back pain. A patient may primarily feel buttock, thigh, or leg symptoms.
Can more than one problem be present?
Yes. Hip arthritis, greater trochanteric pain syndrome, and lumbar spine disease commonly overlap.
For example:
- Hip arthritis may change the way a person walks and overload the outer hip tendons.
- A painful outer hip may cause compensatory movement that aggravates the back.
- Lumbar nerve pain may coexist with arthritis seen on a hip X-ray.
- A patient may have a gluteal tendon problem on one side and arthritis on the other.
This is sometimes called a hip-spine problem. The goal is not simply to find every abnormality on an image. The goal is to determine which problem is driving the symptoms and which treatment is most likely to help first.
How an orthopedic examination separates the causes
A useful hip evaluation includes more than checking where it hurts.
The examination may assess:
- Walking pattern and limp
- Hip range of motion
- Pain with internal and external rotation
- Strength of the hip abductors and flexors
- Tenderness over the greater trochanter
- Balance while standing on one leg
- Lower-back motion
- Straight-leg raise or other nerve tension testing
- Reflexes, sensation, and muscle strength in the leg
- Knee symptoms that may be referring pain upward or downward
A carefully performed examination often narrows the diagnosis before advanced imaging is considered.
Which imaging tests are usually helpful?
X-rays
For persistent hip pain, standing pelvis and hip X-rays are often the most useful first study. They can show arthritis, joint-space narrowing, bone spurs, hip dysplasia, prior injury, and other structural changes.
X-rays do not directly show the bursa, tendons, labrum, or nerves, but they help identify or exclude important joint and bone causes.
Musculoskeletal ultrasound
Musculoskeletal ultrasound can evaluate selected outer-hip tendon and bursal problems. It can also guide a diagnostic or therapeutic injection when appropriate.
Ultrasound is especially useful because the painful area can be examined dynamically while the patient moves. However, the presence of fluid or tendon changes on an image must still be matched to the examination.
MRI
MRI may be considered when symptoms persist despite appropriate treatment, when a significant gluteal tendon tear is suspected, when the diagnosis remains uncertain, or when another problem such as a stress injury, labral tear, avascular necrosis, or tumor needs to be evaluated.
An MRI is not automatically the first test for every patient with hip pain.
Diagnostic injections
A carefully placed anesthetic injection can sometimes help determine whether pain is coming from inside the hip joint or from an outer-hip structure. The response is interpreted together with the history, examination, and imaging. No injection provides a perfect diagnosis by itself.
Treatment depends on the source
Hip arthritis treatment
Early treatment may include:
- Activity modification without complete inactivity
- Low-impact exercise
- Physical therapy to improve strength, mobility, and walking mechanics
- Acetaminophen or an anti-inflammatory medication when medically safe
- Weight management when excess load is contributing to symptoms
- A cane or walking aid for selected patients
- A hip joint injection in appropriate situations
When pain and stiffness remain severe despite nonsurgical care and daily life is substantially limited, hip replacement may be discussed. Surgery should be based on symptoms, examination, imaging, health factors, and the patient’s goals.
Greater trochanteric pain syndrome treatment
Treatment often focuses on reducing compression and improving tendon capacity:
- Avoid sleeping directly on the painful side
- Place a pillow between the knees when lying on the opposite side
- Avoid prolonged standing with the hip pushed outward
- Temporarily reduce hills, stairs, and repetitive side-to-side loading
- Begin progressive hip abductor and core strengthening
- Address gait, balance, and lower-extremity mechanics in physical therapy
- Use ice or anti-inflammatory medication when appropriate
- Consider an image-guided injection for selected patients
- Evaluate for a gluteal tendon tear when weakness or persistent symptoms raise concern
Repeated injections without a clear rehabilitation plan may provide only temporary relief and may not address the underlying tendon problem.
Back-related pain treatment
Treatment varies depending on whether the problem is a disc irritation, spinal stenosis, arthritis, or another cause. Initial care may include activity modification, medication when safe, physical therapy, and a structured home program.
Progressive weakness, significant numbness, balance difficulty, or persistent radiating pain may require a more focused spine evaluation.
What can you do before your appointment?
A few observations can make the visit more productive:
- Note the exact location of the pain with one finger.
- Record whether symptoms travel below the knee.
- Pay attention to numbness, tingling, or weakness.
- Notice whether putting on shoes or getting into a car is difficult.
- Check whether lying on the painful side reliably reproduces symptoms.
- Write down which positions make the pain better or worse.
- Bring prior hip, pelvis, or spine imaging when available.
- List prior treatments and whether they helped temporarily, partially, or not at all.
Avoid repeatedly forcing a painful stretch or exercise just because it is labeled a “hip exercise.” The right exercise for arthritis may aggravate an irritable tendon, and the right tendon program may not address a nerve problem.
When should hip pain be evaluated urgently?
Seek prompt medical care for:
- Inability to bear weight after a fall or injury
- A visibly shortened or rotated leg
- Fever, redness, warmth, or rapidly increasing swelling
- Severe pain that begins suddenly without a clear reason
- New bowel or bladder difficulty
- Numbness in the groin or saddle area
- Rapidly progressive leg weakness
- A cold, pale, or severely swollen leg
- Hip pain with chest pain, shortness of breath, or other concerning systemic symptoms
Persistent pain that interferes with sleep, work, walking, exercise, or daily activities also deserves evaluation even when it is not an emergency.
A practical hip evaluation in Hawaiʻi
At Pacific Bone & Joint, the goal is to identify whether pain is coming from the hip joint, the tissues around the hip, the lower back, or a combination of these areas. Evaluation may include an orthopedic examination, X-rays, musculoskeletal ultrasound, physical therapy, targeted injections, and surgical discussion only when appropriate.
Pacific Bone & Joint serves patients on Oʻahu and Hawaiʻi Island. Request an appointment when hip pain is limiting walking, sleep, work, exercise, or everyday activities.
