Hip pain rarely comes from the bone itself. In most cases, the structures around and inside the hip joint are responsible: tendons, fluid-filled sacs called bursae, the cartilage lining the socket, or even nerves being compressed nearby. Where exactly you feel the pain is the single biggest clue to what’s going on, because different conditions produce pain in predictably different locations.
What the Location of Your Pain Tells You
Hip pain falls into three general zones: the front of the hip and groin, the outer side, and the back near the buttock. Each zone points to a different set of causes.
Front and groin pain usually means something inside the joint itself is irritated. In younger adults, the two most common culprits are labral tears and femoroacetabular impingement (a mismatch in the shape of the ball and socket that causes pinching during movement). In older adults, osteoarthritis is far more likely. All three tend to produce a deep ache in the groin or front of the thigh that gets worse with activity.
Outer (lateral) pain is most often caused by greater trochanteric pain syndrome, an umbrella term that covers irritation of the tendons attaching to the bony bump on the outside of your hip, inflammation of the bursa there, or friction from the band of tissue running down the outside of your thigh. This affects roughly 1.8 per 1,000 people each year and is especially common in runners and people who sleep on one side.
Back and buttock pain is frequently referred from somewhere else. Spinal problems in the lower back, compression of the sciatic nerve deep in the buttock, sacroiliac joint dysfunction, and hamstring tendon issues can all send pain into the hip area even though the hip joint itself is fine.
Greater Trochanteric Pain Syndrome
If the outside of your hip hurts when you walk, sit for a long time, or lie on that side at night, greater trochanteric pain syndrome is the most likely explanation. For years it was written off as simple bursitis, but newer research shows that many of these cases actually involve damage to the gluteus medius tendon, the thick band of tissue that anchors your main hip-stabilizing muscle to the bone.
The distinction matters because a small tendon tear won’t always heal with the same basic rest-and-ice approach that works for bursitis. Full-thickness tears of the gluteus medius cause noticeable weakness: you might feel your pelvis drop on the opposite side when you stand on the affected leg, or you may find it hard to push your leg outward against resistance. Pain with rising from a chair, pain when rotating the hip, and pain that wakes you at night are all hallmarks of gluteal tendon problems rather than straightforward bursa inflammation.
Most moderate cases improve within two to six weeks with physical therapy focused on strengthening the hip stabilizers and modifying activities that aggravate the area. Sticking consistently to the exercise program makes a significant difference in how quickly symptoms resolve.
Labral Tears and Joint Impingement
The labrum is a ring of cartilage that lines the rim of your hip socket, helping to keep the ball of the femur seated properly. When it tears, you typically feel a deep ache in the groin or front of the hip. The hallmark symptom is a clicking, popping, or catching sensation during movement, sometimes accompanied by a feeling that the hip is unstable or might give way.
Labral tears often develop after a sports injury or trauma, but they can also happen gradually when the shape of the joint creates repeated pinching. That pinching is femoroacetabular impingement, one of the most common causes of hip pain in young adults. People with impingement notice restricted movement, particularly when bringing the knee toward the chest, rotating the leg inward, or crossing it toward the opposite side. Activities like squatting, getting in and out of a car, or sitting in low chairs tend to flare it up.
Both conditions are diagnosed through a combination of physical examination and imaging. Standard X-rays can show bone shape abnormalities, but an MRI is typically needed to see the labrum and other soft tissues clearly. MRI can also reveal swelling inside the bone that confirms subtle injuries invisible on X-ray.
Osteoarthritis
In adults over 50, wear-and-tear arthritis of the hip is the most common intra-articular cause of pain. The cartilage cushioning the joint gradually thins, leading to stiffness, aching in the groin or front of the thigh, and reduced range of motion. Morning stiffness that loosens up within 30 minutes or so is a classic pattern. Over time, the hip may feel stiffer getting into shoes or socks, and walking distance gradually shortens.
X-rays usually show joint space narrowing and bone spurs once osteoarthritis is well established. Early stages can look normal on X-ray, which is why persistent pain sometimes warrants an MRI for a clearer picture.
Pain That Comes From Somewhere Else
One of the trickiest things about hip pain is that it often originates in a completely different structure. The lower spine is the biggest offender. A herniated disc or narrowed spinal canal can send pain into the buttock, outer hip, or even down the leg in a pattern that mimics a hip problem. If your pain shoots below the knee, changes with back position, or comes with tingling or numbness, spinal involvement is worth investigating.
Deep gluteal syndrome, which includes the well-known piriformis syndrome, occurs when the sciatic nerve gets compressed by muscles or other structures deep in the buttock. This typically causes posterior hip and buttock pain that worsens with prolonged sitting. Sacroiliac joint dysfunction produces a similar aching near the top of the buttock, often on one side, and tends to flare with transitions like standing up from a chair or rolling over in bed.
Signs That Need Prompt Attention
Most hip pain is not dangerous, but a few patterns warrant urgent evaluation. Pain that develops suddenly after a fall, especially in anyone over 60 or with osteoporosis, could indicate a fracture. A hip that becomes hot, swollen, and extremely painful within hours, particularly with fever, raises concern for a joint infection that needs same-day treatment.
Avascular necrosis, a condition where blood supply to the femoral head is disrupted and bone tissue begins to break down, deserves mention because it starts quietly. Early on there may be no symptoms at all. As it progresses, pain centered in the groin, thigh, or buttock develops gradually, initially only with weight-bearing but eventually present even at rest. Risk factors include long-term corticosteroid use, heavy alcohol use, and previous hip injuries. Because early detection improves outcomes, ongoing or worsening hip pain without a clear mechanical explanation is worth getting checked.
What Helps at Home
While you’re sorting out the cause, a few adjustments can reduce discomfort. If you sleep on your side, placing a pillow between your knees keeps your hips aligned and takes pressure off the outer hip structures. Sleeping on your back with a pillow under your knees serves the same purpose by reducing strain on the joint capsule.
Avoiding the specific postures that provoke your pain is more effective than generic rest. If sitting aggravates it, take standing breaks every 20 to 30 minutes. If walking flares it up, shorten your stride and slow your pace rather than stopping movement entirely. Complete inactivity tends to make hip problems worse over time, not better, because the muscles that stabilize the joint weaken.
Gentle strengthening of the hip abductors and external rotators (the muscles on the outer hip and deep in the buttock) benefits nearly every common cause of hip pain. Simple exercises like side-lying leg raises, clamshells, and bridges build the support system the joint depends on. Starting with low resistance and progressing gradually is key, since pushing too hard too early can irritate inflamed tissues.
How Hip Pain Gets Diagnosed
A thorough physical exam usually narrows the possibilities significantly. Your provider will watch you walk, check your range of motion, and perform specific provocation tests that stress individual structures. Where the pain reproduces during these maneuvers tells a lot about which tissue is involved.
X-rays are typically the first imaging step. They show bone shape, joint spacing, fractures, and arthritis clearly. When soft tissue injury is suspected, such as a labral tear, tendon damage, or a stress fracture that isn’t visible on X-ray, MRI provides the detailed cross-sectional images needed. MRI can reveal bone swelling, cartilage damage, and tendon tears that X-rays simply cannot detect, making it the more useful tool for younger patients with non-arthritic hip pain.
