Left-sided hip pain that flares with walking usually stems from soft-tissue problems around the outer hip rather than from the hip joint itself. The most common umbrella diagnosis is greater trochanteric pain syndrome, a condition once blamed almost entirely on inflamed bursae but now understood to involve tendons, muscles, and the thick band of connective tissue running down the outside of the thigh. Because walking loads these structures with every step, even mild damage can turn an ordinary stroll into a painful chore. The specific cause matters, though, because treatments range from simple activity tweaks to surgery, and what works for one diagnosis may do nothing for another.
Greater Trochanteric Pain Syndrome
Greater trochanteric pain syndrome (GTPS) is the term clinicians now prefer for chronic pain along the outer hip, centered over the bony bump you can feel at the top of your thigh. For years, “trochanteric bursitis” was the standard label, implying that a small fluid-filled sac was inflamed. That label turns out to be misleading for most people. In a large ultrasound study of 877 patients with outer-hip pain, roughly 80 percent did not have bursitis at all. About half had signs of gluteal tendon degeneration, and close to 30 percent had a thickened iliotibial band, while only about one in five actually showed inflamed bursae.1PubMed. Sonography of greater trochanteric pain syndrome and the rarity of primary bursitis So if you have been told you have trochanteric bursitis, the real culprit is more likely a worn or irritated tendon.
GTPS is considered the most common lower-limb tendon-related pain problem, and it hits postmenopausal women especially hard, affecting roughly one in four women over 50.2Wolters Kluwer / JBJS Reviews. Gluteal Tendinopathy: Critical Analysis Review of Current Nonoperative Treatments The pain classically sits on the side of the hip, can radiate down the outer thigh, and worsens with walking, climbing stairs, or lying on the affected side at night. Because the symptoms overlap with other conditions, including degenerative joint disease and even low-back problems, GTPS can mimic pain from many other sources.3PubMed.

Gluteal Tendinopathy and How It Affects Your Walk
When the gluteal tendons themselves begin to break down, the condition is called gluteal tendinopathy. These tendons connect the deep hip muscles to the greater trochanter, and they are responsible for stabilizing your pelvis every time you stand on one leg, which is exactly what you do with each walking stride. Once those tendons weaken, your body compensates in ways you may not even notice until pain stops you.
Research comparing people with gluteal tendinopathy to healthy controls found measurable differences in how the pelvis and hip behave during single-leg stance. The affected group showed more inward drift of the hip and a noticeable pelvic shift toward the painful side when preparing to lift the other leg. During steady single-leg balance, the pelvis on the opposite side dropped lower than it should.4PubMed. Single leg stance control in individuals with symptomatic gluteal tendinopathy That pelvic drop matters because it forces the hip abductor muscles to work harder with each step and changes the pattern of forces traveling through the joint. In adolescent patients with hip pathology, a pelvic-drop gait pattern correlated with more self-reported hip pain and higher demands on the hip abductor muscles, even though the patients’ abductor strength was no different from those without the abnormal gait.5Gait & Posture. Investigating pelvic drop gait abnormality in adolescent hip pathology patients
In practical terms, if you notice a slight waddle or hip-hike when you walk, or if the opposite side of your pelvis seems to dip with each step, that is your body revealing a weakness or pain problem around the hip. A physical therapist can spot it easily from behind, and it is one of the first clues that the tendons need attention rather than, say, the joint itself.
Femoroacetabular Impingement and Labral Tears
Pain that seems to originate deeper inside the hip, often described as a sharp catch or pinch in the groin or front of the hip, points toward problems with the joint itself. Femoroacetabular impingement syndrome (FAIS) occurs when the shape of the ball or socket creates abnormal contact, and it commonly leads to tears in the labrum, the ring of cartilage lining the rim of the socket. FAIS is a painful condition that limits function, and people with it often develop altered walking patterns as the body tries to avoid positions that provoke the pinch.6PubMed Central. Preoperative and Postoperative Walking Gait in Women With Acetabular Labral Tears and Femoroacetabular Impingement Syndrome
Because the pain from impingement tends to be deep and anterior, it is usually distinguishable from the lateral pain of GTPS. But the two can coexist. A systematic review of endoscopic gluteal tendon repairs found that labral tears and cartilage damage were common comorbidities discovered during surgery for outer-hip pain.7PubMed. Labral Tears and Chondral Lesions Are Common Comorbidities Identified During Endoscopic Repair of Gluteal Tendon Tears for Greater Trochanteric Pain Syndrome So someone walking with left-hip pain may actually have both an inner-joint problem and an outer-hip tendon problem feeding off each other.
Nerve-Related Causes
Not all left-hip walking pain comes from bones, tendons, or cartilage. Meralgia paresthetica is a nerve condition caused by compression or injury to the lateral femoral cutaneous nerve, which supplies sensation to the outer and front of the thigh.8PubMed Central. Suprainguinal Lateral Femoral Cutaneous Neurectomy for Recurrent Meralgia Paresthetica: A Technique Guide Instead of a dull ache, the pain is often burning, tingling, or accompanied by numbness. It typically worsens with prolonged standing or walking and improves with sitting.
Tight clothing, belts, weight gain, and prolonged hip flexion can all trigger it, but there may also be a structural component. Case reports have raised the possibility that femoroacetabular impingement can be associated with lateral femoral cutaneous nerve problems, meaning one hip condition could provoke the other.9PubMed Central. Meralgia paresthetica and femoral acetabular impingement: a possible association This is worth knowing because a person treated only for impingement might continue to have nerve-type pain, or vice versa.
An ultrasound-guided nerve block can be both diagnostic and therapeutic. In a case series of 11 patients with meralgia paresthetica, symptom improvement was achieved in 10 of them following a targeted nerve block.10PubMed Central. Ultrasound-Guided Lateral Femoral Cutaneous Nerve Block in Patients with Meralgia Paresthetica: Technical Description and Case Series of 11 Patients If the block relieves the pain, you and your clinician know the nerve is the source.
Leg Length Discrepancy and Biomechanical Loading
Many people have a slight difference in the length of their legs without ever knowing it. Small discrepancies, on the order of a few millimeters, are common and usually painless. However, leg length discrepancy can lead to uneven loading of the hip joints and the lower spine over time.11PubMed Central. Leg length discrepancy and osteoarthritis in the knee, hip and lumbar spine The longer leg tends to absorb more impact with each step, and the shorter leg’s hip often compensates by tilting or hiking. Over years, that asymmetric stress could contribute to pain on one side only.
That said, the effect on walking is less dramatic than most people assume. Experimental data suggest that a leg length difference of about 20 millimeters alone has little effect on gait trajectory.12PubMed. Effect of limited range of motion of the hip joint and leg-length discrepancy on gait trajectory The problem becomes more significant when limited hip range of motion is also present, because the body loses the compensatory flexibility that normally masks the discrepancy. If you have left-hip pain only when walking, and you also feel stiff in that hip, a combination of mild leg length difference and reduced motion could be at play.
Why the Left Side Specifically
There is no inherent anatomical reason the left hip would be more vulnerable than the right. Both hips have the same tendons, bursae, and nerve pathways. But daily habits can create asymmetry. Most people are right-hand dominant, which means the left leg often serves as the stance leg more frequently, absorbing more single-leg load during tasks like stepping, reaching, and pivoting. Carrying bags, children, or groceries predominantly on one side also imposes asymmetric demands on the trunk and pelvis. A study of young adults walking with a one-sided 5-kilogram handbag found that the load significantly altered both trunk movement patterns and spinal muscle activity, creating a compensatory strategy that stresses the hip on the loaded side differently from the other.13International Journal of Advances in Engineering and Pure Sciences. Impact of Unilateral Handbag Loads on Spine–Hip Kinematics and Paraspinal Muscle Activities: A PCA-Based Analysis
If your left-hip pain appeared without any clear injury, it is worth reviewing your movement habits: which side do you tend to lean on, carry things on, or cross your legs toward? These patterns alone do not cause tendon degeneration, but they can tip a borderline tendon into a painful one.
What to Expect During Diagnosis
Clinicians typically start with a physical exam that reproduces your symptoms. For suspected GTPS or gluteal tendinopathy, a few bedside tests are surprisingly accurate. Standing on the affected leg while the clinician watches for pain and pelvic control has been reported with very high sensitivity and specificity when correlated with MRI findings. Tenderness over the bony prominence, a positive resisted hip abduction test, and a specific “hip lag sign” all help narrow the diagnosis without imaging.14PubMed Central. Pathogenesis and contemporary diagnoses for lateral hip pain: a scoping review
Imaging is typically reserved for cases where the physical exam is ambiguous or where surgical planning requires a closer look. Ultrasound can reveal tendon thickening, tears, and the presence or absence of bursitis in real time. MRI gives a more detailed view of both soft tissue and the joint itself, which is useful when impingement or labral tears are suspected. X-rays are helpful mainly for ruling out arthritis, stress fractures, or bony abnormalities. In many straightforward cases of lateral hip pain, however, a skilled clinician can confidently diagnose the problem with hands and eyes alone.
Conservative Treatment
Most people with left-sided hip walking pain start with non-surgical treatment, and most improve with it. The first-line approach for GTPS and gluteal tendinopathy combines activity modification, anti-inflammatory medication, and physical therapy.2Wolters Kluwer / JBJS Reviews. Gluteal Tendinopathy: Critical Analysis Review of Current Nonoperative Treatments Activity modification does not mean resting completely. It means reducing the specific loads that provoke pain: cutting back on hill walking, avoiding crossing your legs, not sleeping on the sore side, and staying off exercises that involve deep stretches into hip adduction.
Physical therapy for gluteal tendinopathy has evolved considerably. Traditional stretching and foam rolling of the iliotibial band, once standard advice, can actually compress the tendons against the bone and worsen symptoms. Current best practice emphasizes progressive loading: starting with isometric holds (pressing the leg outward against a wall, for example) and gradually advancing to standing exercises that mimic the demands of walking and stairs. The goal is to build the tendon’s tolerance to load rather than merely reducing inflammation.
One question people often ask is whether shoe inserts help. A study of women with GTPS found that medially posted foot orthoses did not significantly change hip biomechanics or pain during walking compared to flat insoles or no insoles.15PubMed. Do posted foot orthoses alter hip biomechanics and pain during walking in women with greater trochanteric pain syndrome? That does not mean orthotics are useless for every hip condition, but for typical lateral hip pain, they are unlikely to be the answer on their own. Spending money on custom insoles before trying a structured exercise program is generally putting the cart before the horse.
Injections and When to Consider Them
Corticosteroid injections have been the go-to shot for trochanteric pain for decades. They can provide quick relief by dampening inflammation, and many people feel substantially better within a week or two. The problem is that the relief often fades, and repeated steroid injections into a tendon can weaken it further over time. For people with true gluteal tendinopathy rather than bursitis, the short-term fix may not address the underlying structural issue.
Platelet-rich plasma (PRP) injections are increasingly offered as an alternative. In a randomized controlled trial comparing a single PRP injection with a single corticosteroid injection for gluteal tendinopathy, both groups had similar pain and function scores at two and six weeks. By 12 weeks, however, the PRP group showed significantly better function scores, and a larger proportion of PRP recipients reached a clinically meaningful improvement: about 82 percent in the PRP group compared with about 57 percent in the steroid group.16PubMed. The Effectiveness of Platelet-Rich Plasma Injections in Gluteal Tendinopathy PRP is not a miracle cure, and it is rarely covered by insurance, but for patients who want something beyond a steroid and are not yet ready for surgery, the evidence is encouraging.
When Surgery Becomes Necessary
Surgery for lateral hip pain is reserved for people who have tried conservative treatment thoroughly and still have significant pain and functional limitation. Patients with gluteal tendon tears often go through multiple rounds of non-surgical management with only temporary relief before surgical repair is considered.17PubMed. A review of surgical repair methods and patient outcomes for gluteal tendon tears
The surgical options include open or endoscopic tendon repair, sometimes with bone anchors, and in severe cases, tendon reconstruction or transfer. Both open and endoscopic techniques have demonstrated improvements in patient-reported pain and function, with low complication and retear rates for both partial and full-thickness tears.18PubMed Central. Surgical Treatment and Outcomes for Gluteal Tendon Tears When endoscopic repair is performed, surgeons often also remove the inflamed bursa. A systematic review of these procedures found that pain and functional outcomes improved significantly in nearly all reported studies, and that labral tears and cartilage lesions were frequently discovered and addressed at the same time.7PubMed. Labral Tears and Chondral Lesions Are Common Comorbidities Identified During Endoscopic Repair of Gluteal Tendon Tears for Greater Trochanteric Pain Syndrome
For impingement and labral tears causing deep groin or anterior hip pain, arthroscopic surgery to reshape the bone and repair the labrum is a separate procedure from gluteal tendon repair, though as noted, both problems can coexist and be addressed in the same operation when needed.
Hormonal Factors and Why Women Are Hit Harder
The striking sex difference in GTPS deserves its own discussion. As estrogen levels drop after menopause, collagen production declines and tendons become thinner. Rates of tendon pathology and the likelihood of tendon rupture rise.19PubMed Central. Does menopausal hormone therapy (MHT), exercise or a combination of both, improve pain and function in post-menopausal women with greater trochanteric pain syndrome (GTPS)? A randomised controlled trial This is consistent with what we see clinically: women in their fifties and sixties make up the majority of GTPS cases, and many describe a gradual onset that coincides roughly with perimenopause or menopause.
Supplemental estrogen preserves bone mass, increases skeletal muscle strength, and prevents a decline in skin collagen. It is plausible that it could also preserve tendon collagen and reduce tendon degeneration, though the evidence for this specific application is still being built.19PubMed Central. Does menopausal hormone therapy (MHT), exercise or a combination of both, improve pain and function in post-menopausal women with greater trochanteric pain syndrome (GTPS)? A randomised controlled trial Women experiencing hip pain around menopause should be aware that the hormonal shift may be a contributing factor, not just “aging,” and that targeted tendon-loading exercises may be especially important during that transition.
Anatomical differences also play a role. Women generally have wider pelvises, which increases the angle at which the gluteal tendons pull on the greater trochanter. A larger angle means greater compressive load on the tendon where it wraps around the bone, making it more vulnerable to wear over time. Combined with the hormonal changes, this helps explain why the condition is so heavily skewed toward women.
When Pain Outlasts the Injury
Some people develop hip pain that seems disproportionate to what imaging shows, or the pain persists long after conservative treatment should have helped. This disconnect can be frustrating, and one explanation lies in how the nervous system processes pain over time. In a study of patients with hip osteoarthritis, scores on a questionnaire measuring features of central sensitization correlated with pain at rest, even after accounting for the severity of the joint disease itself. The average score was relatively low across the group, but about 5 percent of patients scored in a range suggesting a significant sensitization component.20PubMed Central. Central sensitization inventory scores correlate with pain at rest in patients with hip osteoarthritis: a retrospective study
Central sensitization means the nervous system has turned up its volume dial. Normal signals from the hip that should register as mild discomfort get amplified into significant pain. Walking, which rhythmically loads the hip, can become disproportionately painful. Recognizing this pattern matters because the treatment approach changes: rather than more injections or more aggressive physical therapy aimed at the tissue, strategies that calm the nervous system, including graded exposure to movement, pain education, sleep improvement, and sometimes medication targeting nerve sensitivity, become more appropriate. If you have been through the usual treatments and your left-hip pain during walking does not match what your scans show, a conversation about pain processing with your clinician could be a productive next step.
