Hip soreness has dozens of possible causes, and the single best clue to narrowing yours down is where exactly you feel it. Pain on the outer side of the hip, deep in the groin, or in the buttock each point to a different set of structures. About 14% of adults over 60 report significant hip pain on most days, and women are affected more often than men, but hip soreness can show up at any age depending on the cause.
Where It Hurts Matters Most
The hip is a deep ball-and-socket joint surrounded by layers of muscle, tendon, and bursa (fluid-filled cushions). When people say “my hip is sore,” they’re usually pointing to one of three zones: the outer hip, the front of the hip near the groin, or the back of the hip into the buttock. Each zone has its own common culprits, so pinpointing the location is the fastest way to figure out what’s going on.
Outer Hip Soreness
Pain along the outside of the hip, especially right over the bony point you can feel when you press, is most often caused by a condition called greater trochanteric pain syndrome. This is an umbrella term that covers irritation of the tendons attaching your glute muscles to the bone, inflammation of the bursa that cushions those tendons, and friction from the thick band of tissue running down the outside of your thigh.
The hallmark of this problem is pain when lying on the affected side at night. You’ll also notice tenderness when you press directly over the outer hip, and the soreness often flares with activities like climbing stairs, walking uphill, or standing on one leg. It’s one of the most common causes of hip pain in middle-aged adults and is frequently triggered by a change in activity level, like suddenly walking more on vacation or starting a new exercise routine.
Front Hip or Groin Soreness
Soreness deep in the front of the hip or into the groin usually points to something happening inside the joint itself or in the muscles that cross the front of it.
Osteoarthritis
In adults over 50, the most common intra-joint cause is osteoarthritis, where the cartilage lining the socket gradually wears down. The classic pattern is stiffness and soreness first thing in the morning or after sitting for a while that loosens up with movement. Over time, you may notice your hip doesn’t rotate as freely as it used to, and walking may become uncomfortable enough to cause a slight limp. If your morning stiffness lasts about 30 minutes or less before easing, that pattern is typical of osteoarthritis rather than inflammatory arthritis, which tends to cause longer-lasting morning stiffness.
Labral Tears
In younger and more active adults, a tear in the ring of cartilage that lines the rim of the hip socket (the labrum) is a frequent source of groin-area pain. The telltale sign is a clicking, catching, or locking sensation during certain movements, especially when you rotate your leg or bring your knee toward your chest. Labral tears often develop from repetitive motions in sports like soccer, hockey, or dance, or from a structural mismatch between the ball and socket that causes the bones to pinch the labrum during deep bending.
Muscle Strains and Stress Fractures
The hip flexor muscles running across the front of the joint can strain or tear, causing sharp pain when you try to lift your knee. This is common in runners and sprinters. Stress fractures in the neck of the thighbone are another overuse injury, typically seen in distance runners or athletes whose training load has increased too quickly. These fractures cause a deep, aching soreness that worsens with weight-bearing activity and improves with rest.
Buttock and Posterior Hip Soreness
Soreness in the back of the hip or deep in the buttock is tricky because it can originate from the hip itself, the lower back, or the nerves running between the two.
Lower back problems are one of the most common sources of pain that feels like it’s in the hip. A bulging disc or arthritis in the lumbar spine can send pain into the buttock and down the leg without ever causing noticeable back pain. Sacroiliac joint dysfunction, where the joint connecting the base of the spine to the pelvis becomes irritated, also produces deep buttock soreness that can mimic a hip problem.
Deep gluteal syndrome is another possibility. This happens when the sciatic nerve gets pinched by muscles deep in the buttock, most commonly the piriformis. People with this condition generally have more pain with walking and sometimes feel relief when sitting. The pain centers near the middle of the buttock and can refer down the back of the leg toward the knee in more severe cases. A history of repeated hamstring injuries or chronic low back issues can predispose you to this kind of nerve irritation.
Hamstring tendon problems also cause posterior hip soreness, specifically around the sit bone (the bony point you feel when you sit on a hard surface). This is common in runners and people who do a lot of forward bending or high-speed sprinting.
How to Tell Nerve Pain From Joint Pain
One of the most useful distinctions is whether your soreness stays localized to the hip area or travels down your leg. True hip joint pain tends to stay in the groin or outer hip. Pain that shoots, burns, or tingles down the back or side of the thigh usually involves a nerve, either from the spine or from compression somewhere along the buttock.
Another clue is what makes it worse. Joint pain typically flares with weight-bearing and eases with rest. Nerve-related pain can worsen with specific positions like prolonged sitting, crossing your legs, or taking long strides while walking. If taking bigger steps reproduces your symptoms, that can point toward a nerve being compressed between the bones of the pelvis during hip extension.
Common Triggers That Aren’t Injuries
Not all hip soreness comes from a specific injury or structural problem. Some of the most frequent triggers are surprisingly mundane. Sitting for long periods, especially in low chairs or bucket seats, can irritate the hip flexors and compress the structures in the buttock. Sleeping on one side without a pillow between your knees puts sustained pressure on the outer hip bursa. A sudden increase in walking or running volume, even a weekend of extra activity, can inflame tendons that weren’t conditioned for the load.
Weight changes matter too. Every extra pound of body weight translates to roughly three additional pounds of force across the hip joint during walking. Footwear can also play a role: worn-out shoes or a sudden switch to flat, unsupportive shoes changes the mechanics traveling up the leg to the hip.
When Hip Soreness Needs Attention
Most hip soreness from overuse or minor strain improves within one to two weeks with rest, ice, and gentle stretching. Certain patterns, though, signal something more serious. Severe pain after a fall, inability to put weight on the leg, or a hip that looks swollen and feels warm needs immediate evaluation. A fever combined with hip pain can indicate infection in the joint, which is a medical emergency.
Outside of those urgent situations, it’s worth getting evaluated if your hip soreness lasts longer than two weeks, disrupts your sleep, stops you from doing your normal activities, or keeps coming back. Morning stiffness lasting 30 minutes or more on a regular basis also warrants a closer look, as it can point toward inflammatory conditions that benefit from early treatment.
For most people, a clinician can identify the likely cause through a physical exam that tests your hip’s range of motion in specific directions and applies resistance to isolate different muscle groups. Imaging like X-rays or MRI is usually reserved for cases where the exam findings are unclear or symptoms haven’t responded to initial treatment.
