Hip soreness stems from dozens of possible causes, ranging from a simple muscle strain that resolves in days to conditions like osteoarthritis or a labral tear that may need long-term management. The location of the pain, how it started, and what makes it worse all offer strong clues about what is going on inside the joint or surrounding tissues. Most hip pain is not dangerous, but a few patterns, particularly pain paired with fever, sudden inability to bear weight, or pain after a fall in someone with fragile bones, warrant prompt medical attention.
Where Exactly Does It Hurt?
One of the most useful things you can do before seeing a doctor is pinpoint where the soreness is. Hip pain is broadly grouped into three zones: anterior (front of the hip or groin), lateral (the outer side), and posterior (the buttock area). Each zone points toward a different family of problems. Anterior hip pain is further divided into causes originating inside the joint itself, such as labral tears, osteoarthritis, and osteonecrosis, and causes arising from structures outside the joint, such as snapping hip syndrome and athletic pubalgia.

Posterior, Lateral, and Anterior Hip Pain Due to Musculoskeletal Origin: A Narrative Literature Review of History, Physical Examination, and Diagnostic ImagingPain along the outer hip, meanwhile, usually involves the tendons and bursae around the bony bump you can feel on the side of your thigh, the greater trochanter. And posterior hip pain often involves the piriformis, hamstring tendons, or the sacroiliac joint farther back. Knowing the zone will not give you a diagnosis on its own, but it narrows the field considerably and helps a clinician decide which tests to order first.
Osteoarthritis of the Hip
Osteoarthritis is the single most common reason for chronic hip soreness in adults over about 50. Cartilage inside the ball-and-socket joint gradually wears down, leading to stiffness, aching, and eventually bone-on-bone contact. The pain typically shows up in the groin or front of the hip and is worse with activity, though many people also notice stiffness after sitting for a long time. Risk factors include age, prior hip injuries, obesity, and genetics.
2Europe PMC. Hip Osteoarthritis: A PrimerAn interesting wrinkle is that the severity of arthritis on an X-ray does not always match how much pain someone feels. A study of hip osteoarthritis patients found no significant difference in radiologic severity between those reporting strong pain and those with mild pain. Instead, the researchers found that differences in how the central nervous system processes pain signals appeared to explain the gap. In other words, two people with similar-looking X-rays can have very different pain experiences, and that difference seems to live partly in the nervous system rather than purely in the joint.

If your pain is on the outer side of the hip, the classic culprit used to be called trochanteric bursitis. That label is falling out of favor. Research has shown that the problem is usually damage to the gluteus medius or gluteus minimus tendons rather than straightforward inflammation of the bursa.
4PubMed. MRI and US of gluteal tendinopathy in greater trochanteric pain syndromeThe broader umbrella term now used is greater trochanteric pain syndrome, or GTPS, which covers gluteal tendinopathy, bursitis, and abductor tears.
5PubMed Central. Pathogenesis and contemporary diagnoses for lateral hip pain: a scoping reviewGTPS tends to affect middle-aged women more than men and is common in runners, though it also shows up in sedentary people. The hallmark symptom is tenderness when you press on the bony point of your outer hip, and the pain often worsens when lying on that side at night or climbing stairs. It can be stubborn, lasting months, but targeted strengthening of the gluteal muscles is one of the most reliable treatments. A study of patients with hip instability found that abductor-strengthening exercises improved muscle strength by roughly 16 percent and significantly reduced pain scores, while also making the hip more stable during walking.
6Isokinetics and Exercise Science. Dynamic hip stability, strength and pain before and after hip abductor strengthening exercises for patients with dysplastic hipsFemoroacetabular Impingement and Labral Tears
Femoroacetabular impingement, usually shortened to FAI, is a structural mismatch between the ball and socket of the hip that causes abnormal contact during movement. One version involves extra bone on the femoral head (the ball), and another involves overcoverage by the socket rim. Many people have a combination of both. Over time, the repetitive abutment damages the labrum, a ring of cartilage lining the socket, and can wear down the joint surface.
7PubMed Central. Femoroacetabular impingement: a review of diagnosis and managementFAI and labral tears typically cause deep groin pain that worsens with activities involving hip flexion, like sitting for long stretches, squatting, or pivoting. The pain can feel sharp with certain movements and dull the rest of the time. These problems are increasingly recognized in younger, active adults who previously might have been told nothing was wrong because their X-rays looked normal. MRI with contrast is the usual next step when impingement is suspected, though a clinical exam alone can be surprisingly effective at spotting labral tears. One systematic review found that the FADIR test (bending the hip up, across the body, and rotating it inward) had sensitivity as high as 100 percent for detecting labral pathology, while the FABER test showed specificity up to 100 percent when compared against surgical findings.
8PubMed Central. Sensitivity and Specificity for Physical Examination Tests in Diagnosing Prearthritic Intra-Articular Hip Pathology Are Highly Variable: A Systematic ReviewAnother study found that clinical physical examination had a sensitivity of 94 percent for labral tears, actually outperforming MRI with contrast, which came in at 67 percent.
9PubMed. Clinical Physical Exam Shows High Sensitivity for Detecting Labral Tears in Individuals With Femoroacetabular Impingement SyndromeMuscle Strains and Tendon Injuries
The hip is surrounded by some of the body’s largest and strongest muscles, and any of them can be strained. The iliopsoas, a deep hip flexor, is a frequent offender in runners and athletes who rapidly increase their training load. The iliopsoas acts as a major decelerator during the swing phase of running, so overloading it with too many miles too soon can produce a nagging pain at the front of the hip that persists even after rest.
10PubMed Central. The Rehabilitation of a Runner with Iliopsoas Tendinopathy Using an Eccentric-Biased Exercise – A Case ReportIn people under 65, the most common iliopsoas injuries are muscle strains and partial tendon tears, usually linked to sports.
11PubMed. Iliopsoas injury: an MRI study of patterns and prevalence correlated with clinical findingsHamstring strains and adductor (inner thigh) pulls are also common sources of pain that can feel like it is coming from the hip. The distinguishing feature of a simple strain is that the pain usually has a clear onset tied to a specific activity, responds to relative rest and gradual loading, and improves within weeks. If yours has been lingering for months without improvement, it is worth considering that something else is going on.
Inflammatory and Autoimmune Conditions
Rheumatoid arthritis, ankylosing spondylitis, and other inflammatory joint diseases can target the hip. Rheumatoid arthritis in the hip is easy to miss early on. One study using ultrasound to look at the hips of patients with early rheumatoid arthritis found that many had evidence of joint inflammation even when their hips felt fine clinically, and those who did have symptoms described them as only mild.
12Annals of the Rheumatic Diseases. Hip involvement in early rheumatoid arthritisThese autoimmune conditions tend to cause pain and stiffness that is worst in the morning and improves with movement, the opposite pattern of osteoarthritis, which tends to worsen with activity. If your hip soreness is accompanied by stiffness lasting more than 30 minutes each morning, swelling in other joints, or fatigue, an inflammatory cause is worth investigating. Blood tests for markers like CRP and ESR, along with imaging, can help a rheumatologist sort it out.
When to Worry
Most hip pain is not an emergency, but a few scenarios call for urgency. The combination of hip pain, fever, and inability to bear weight raises the possibility of a septic joint, a bacterial infection inside the hip that can cause serious damage within hours. An initial workup should include joint aspiration. Patients with an inability to bear weight, fever above roughly 38.6°C (about 101.5°F), and elevated inflammatory markers are typically referred for aspiration promptly.
13PubMed Central. Acute Destructive Hip Septic Arthritis in a Young Adult Patient: Case ReportSometimes, hip pain with fever turns out not to be a septic joint but rather an infection of the surrounding muscle or bone, such as pyomyositis, which still requires urgent treatment.
14PubMed. Hip pain and fever: when it’s not a septic joint, what’s next?Another red flag is hip pain after a fall in someone at risk for osteoporosis. A stress fracture of the femoral neck can be subtle, sometimes presenting as vague groin or hip pain without a dramatic break. If the fracture goes unrecognized, it can compromise blood supply to the femoral head and lead to avascular necrosis, a condition where the bone tissue dies. An early MRI is recommended when a stress fracture is suspected, precisely to avoid that outcome.
15Vojnosanitetski pregled. Avascular necrosis of the femoral head following an occult femoral neck stress fractureOther reasons to see a doctor sooner rather than later include sudden severe pain without injury, hip pain that wakes you from sleep regularly, and pain that has not improved after two to three weeks of rest and home care.
Injections and Their Limits
Corticosteroid injections into the hip joint can provide meaningful short-term pain relief for osteoarthritis. Randomized controlled trials show they offer both pain reduction and functional improvement.
16PubMed Central. Intraarticular Corticosteroids for Hip Osteoarthritis: A ReviewA higher dose of corticosteroid appears to produce more sustained relief, with significant pain reduction lasting up to about 12 weeks. Hyaluronic acid injections have had mixed results and generally seem less effective than corticosteroids for osteoarthritis.
17Journal of Hip Preservation Surgery. Symposium: evidence for the use of intra-articular cortisone or hyaluronic acid injection in the hipThere is an important distinction here between using injections for arthritis versus for impingement or labral tears. In the setting of FAI and labral pathology, corticosteroids have little therapeutic benefit and carry a theoretical risk of cartilage damage. They should not be used routinely for those conditions. In practice, a cortisone shot into the hip is sometimes used as a diagnostic tool: if the injection temporarily eliminates the pain, it confirms that the pain source is inside the joint rather than in the surrounding muscles or tendons. But it should not be mistaken for a treatment for structural problems like labral tears.
When Surgery Enters the Picture
Hip arthroscopy, a minimally invasive procedure using small incisions and a camera, has become common for treating labral tears and impingement in younger patients. But outcomes depend heavily on how much arthritis is already present. In patients without significant arthritis, only about 8 percent went on to need a total hip replacement within about two years of arthroscopy. In patients who already had arthritis, that figure jumped to roughly 23 percent, with the average time to replacement being shorter.
18Journal of Hip Preservation Surgery. Can hip arthroscopy in the presence of arthritis delay the need for hip arthroplasty?A large population-based study found an overall two-year conversion rate from arthroscopy to total hip replacement of about 12 percent. Age was a strong predictor: patients under 40 had only a 3 percent conversion rate, while those between 60 and 69 had a 35 percent rate. Obesity and existing osteoarthritis at the time of arthroscopy also increased the odds. Interestingly, patients treated at high-volume centers had lower conversion rates than those at lower-volume centers.
19PubMed. Use of Hip Arthroscopy and Risk of Conversion to Total Hip Arthroplasty: A Population-Based AnalysisTotal hip replacement, meanwhile, remains one of the most successful operations in modern medicine for advanced arthritis. For people with bone-on-bone disease who have exhausted conservative treatments, replacement reliably restores mobility and dramatically reduces pain. But it is a major procedure with a finite lifespan for the implant, which is why surgeons generally try to delay it in younger patients.
How Shoes Affect Hip Load
This is an angle most people do not consider. A study using instrumented hip prostheses measured the actual forces on the joint during walking in different footwear. Compared to barefoot walking, everyday shoes increased the peak contact force on the hip by roughly 35 percent at heel strike. The bending moment on the joint increased even more, by about 47 percent. Shoes with stiff soles or elaborate cushioning and guiding elements produced the highest additional loads.
20Nature / Scientific Reports. Analysis of hip joint loading during walking with different shoe types using instrumented total hip prosthesesThe takeaway is not that everyone should ditch shoes. Rather, if you have chronic hip pain and spend all day in stiff-soled dress shoes or highly structured athletic shoes, experimenting with more flexible, minimal footwear around the house or during low-impact activities could be worth trying. The bare-foot-style shoe in the study produced the lowest increases in joint load. This does not mean minimalist shoes are universally better for everyone; someone with foot problems may need structured support. But for hip pain specifically, excessive shoe stiffness is an underappreciated contributor.
Why Human Hips Are Vulnerable in the First Place
It is worth stepping back for a moment to appreciate that the human hip is doing something biomechanically remarkable and inherently costly. Research into the evolutionary origins of hip problems suggests that the structural features that make our pelvis efficient for bipedal walking also make it more vulnerable to fracture and degeneration. The trade-off for efficient upright locomotion is a hip architecture that puts certain structures under sustained, repetitive stress. This vulnerability is made worse by reduced physical activity and a sedentary lifestyle.
21Communications Biology. Evolutionary roots of the risk of hip fracture in humansThis evolutionary framing is useful because it resets expectations. The hip was not designed for a lifetime of sitting in office chairs interspersed with occasional bursts of exercise. It was shaped for constant, varied, low-to-moderate-level movement. Much of the hip soreness that sends people searching for answers is, at root, a mismatch between how the joint evolved to be used and how modern life actually uses it. Strengthening the muscles around the hip, maintaining a healthy weight, and staying consistently active are not just generic health advice; they directly address the mechanical vulnerability the joint was born with.
Hip Pain in Children and Teenagers
Hip pain in younger age groups has a different set of likely causes than in adults. In teenagers, especially those who are overweight and going through a growth spurt, one condition to watch for is slipped capital femoral epiphysis (SCFE), in which the ball of the hip slips backward on the growth plate. SCFE typically causes pain in the groin, thigh, or knee (yes, knee pain can be referred from the hip) and a noticeable limp. It requires urgent surgical stabilization to prevent further displacement.
In younger children, transient synovitis (a temporary inflammation of the joint lining, often following a viral illness) is the most common cause of sudden hip pain and limping. It usually resolves on its own within a week or two. The challenge is that it can look identical to septic arthritis at first, which is why a child with acute hip pain and fever should be evaluated quickly. Other childhood causes include Legg-Calvé-Perthes disease, where blood supply to the femoral head is temporarily disrupted, causing bone changes that need monitoring over months to years.
When Pain Does Not Match the Damage
The disconnect between visible joint damage and felt pain deserves emphasis because it affects treatment decisions. As noted earlier, research in hip osteoarthritis patients has demonstrated that people with severe pain do not necessarily have worse-looking joints on imaging, and the difference appears related to central sensitization, a state where the nervous system amplifies pain signals.
3PubMed Central. Association of Chronic Pain with Radiologic Severity and Central Sensitization in Hip Osteoarthritis PatientsThis matters practically because if your pain is being amplified by how your nervous system processes signals rather than by the severity of the structural problem, purely structural interventions like surgery may not give you as much relief as expected. Clinicians who recognize central sensitization may recommend treatments that target pain processing, including exercise, cognitive behavioral therapy, and sometimes medications that calm the nervous system, alongside or instead of procedures aimed at the joint itself. If you have been told your imaging looks “not that bad” but you are in significant pain, that does not mean the pain is not real. It means the pain may be coming from more than one source, and treatment needs to address both the joint and the nervous system.
