Hip pain is one of the most common joint complaints in adults, and its meaning depends largely on where you feel it, how it started, and what makes it worse. The hip is a deep ball-and-socket joint surrounded by layers of muscle, tendon, and bursa, so pain in the “hip area” can come from the joint itself, the soft tissues around it, or even your lower back. Understanding the location and pattern of your pain is the fastest way to narrow down what’s going on.
Where You Feel It Matters
The hip region is broad enough that people use the word “hip” to describe pain in very different spots. Each location points toward a different set of causes, so pinpointing where the pain is sharpest helps make sense of it.
Front of the hip or groin: Pain deep in the groin or the front crease of the hip usually involves the joint itself. Osteoarthritis, labral tears, and structural impingement (where the bones of the joint don’t glide smoothly) are the most common culprits. Groin pain that worsens when you bring your knee toward your chest or rotate your leg inward is a classic sign of something going on inside the joint. Hip flexor tendon irritation can also cause front-of-hip pain, especially in runners or people who sit for long stretches.
Side of the hip: Lateral hip pain, felt over the bony bump on the outside of your thigh, is rarely the joint. It’s almost always the soft tissue. The most common cause is irritation of the bursa or the gluteal tendons that attach at that spot, sometimes called greater trochanteric pain syndrome. The hallmark is point tenderness right over the bone, pain that radiates down the outer thigh, and pain that’s worst when you lie on that side at night.
Back of the hip or buttock: Pain behind the hip often originates in the lower back or the sacroiliac joint rather than the hip joint itself. Sciatica, piriformis irritation, and deep gluteal syndrome all produce pain in this area. Hamstring tendon problems near their attachment point can also feel like deep buttock pain, particularly when you’re sitting on hard surfaces or bending forward.
Osteoarthritis: The Most Common Cause Over 50
If you’re over 50 and noticing a gradual, worsening ache in your groin or deep hip, osteoarthritis is the most likely explanation. The cartilage cushioning the joint wears down over time, leading to stiffness, reduced range of motion, and pain that’s worst with weight-bearing activity. In the Framingham community study, about 20% of adults over 50 had X-ray evidence of hip arthritis, though only about 4% had both the X-ray changes and consistent pain. That gap means many people have early wear without symptoms, and some people have significant pain before imaging shows much damage.
A few physical signs point strongly toward osteoarthritis. Pain in the groin combined with limited internal rotation (difficulty turning your foot inward while your knee is bent) is one of the most reliable indicators. Stiffness that’s worst in the morning or after sitting, then loosens up with a few minutes of movement, is another hallmark. The pain tends to build over months or years rather than appearing suddenly.
Soft Tissue Problems
Not all hip pain comes from the joint. Bursitis and tendon irritation are extremely common and often mistakable for a joint problem.
Greater trochanteric pain syndrome causes aching on the outer hip that can radiate partway down the thigh but shouldn’t travel below the knee. It’s aggravated by walking, climbing stairs, running, and especially by lying on the affected side. Many people first notice it at night when they roll onto that hip. On examination, pressing directly over the outer hip bone reproduces the pain. This condition responds well to rest, stretching, and targeted strengthening, though it can be stubborn if you keep aggravating it.
Snapping hip syndrome is another soft tissue issue that produces an audible or palpable snap around the hip. The external type happens when a thick band of tissue on the outer thigh slides over the bony prominence during movement. You can often see or feel the snap, though it’s not always painful. The internal type involves a tendon near the front of the hip catching on bone as the hip moves from a bent to a straight position, and this one is usually audible. A third, less common type involves something loose inside the joint itself, like a torn piece of cartilage, which produces more of a clicking or catching sensation.
Labral Tears and Impingement
The labrum is a ring of cartilage that lines the rim of the hip socket, helping to seal and stabilize the joint. Tears in this cartilage are common in active people, especially athletes who do repetitive hip rotation like soccer players, dancers, and hockey players. The pain is typically felt deep in the groin or front of the hip. Mechanical symptoms are the distinguishing feature: clicking, catching, or a feeling that the hip locks or gives way during certain movements.
Labral tears often occur alongside femoroacetabular impingement, a condition where the shape of the hip bones causes them to pinch the labrum during movement. Pain from impingement tends to come on with deep squatting, prolonged sitting, or turning the hip inward. This combination is one of the most common causes of hip pain in younger adults (20s through 40s) who are otherwise healthy and active.
When the Problem Isn’t the Hip
One of the trickiest aspects of hip pain is that it frequently comes from somewhere else. The nerves that supply sensation to the hip and groin exit the lower spine, so problems in the lumbar vertebrae can produce pain that feels exactly like a hip problem. This is common enough that orthopedic specialists have a name for the diagnostic challenge: hip-spine syndrome.
Lower back issues like disc herniations, spinal stenosis, and nerve root irritation can all refer pain into the groin, buttock, thigh, and even down to the knee. If your hip pain came on around the same time as back stiffness, if it changes with different sitting or standing positions, or if it’s accompanied by tingling or numbness in your leg, the source may be your spine rather than your hip. People with both hip arthritis and lumbar spine problems sometimes need both areas addressed before the pain improves.
Less Common but Serious Causes
Most hip pain is caused by wear, overuse, or muscle imbalance. But a few less common conditions are worth knowing about because they require prompt treatment.
Osteonecrosis (also called avascular necrosis) occurs when blood supply to the head of the thighbone is disrupted, causing the bone to weaken and eventually collapse. The biggest risk factors are long-term use of high-dose corticosteroids, heavy alcohol use, a previous hip fracture or dislocation, and certain medical treatments like chemotherapy or radiation. Early on, there may be no symptoms at all. The first sign is usually pain during weight-bearing that gradually worsens. Eventually the joint stiffens, and if the bone surface collapses, pain can intensify suddenly. Catching this early makes a significant difference in outcomes.
Stress fractures of the hip, particularly of the femoral neck, can occur in distance runners, military recruits, and people with weakened bones from osteoporosis. The pain is usually felt in the groin and worsens with activity but improves with rest. These fractures need prompt attention because a complete break can displace the bone and complicate treatment significantly.
Signs That Need Urgent Attention
Most hip pain is safe to monitor and manage at home for a few weeks. However, certain patterns warrant immediate evaluation. Severe hip pain after a fall or injury, especially if you can’t bear weight, needs emergency assessment to rule out a fracture. The same applies if you have tingling or loss of feeling in your hip or leg after an injury.
Outside of trauma, seek urgent care if your hip pain started suddenly without an obvious cause, the joint is swollen and warm, the skin around the hip has changed color, or you have hip pain combined with fever or chills. These signs can indicate infection in the joint, which is a medical emergency.
What Helps Hip Pain at Home
For most non-urgent hip pain, a structured approach to movement and strengthening is the most effective first step. The American Academy of Orthopaedic Surgeons recommends a hip conditioning program done two to three days per week for four to six weeks as a starting point. The program combines stretching and strengthening, beginning with a five to ten minute warm-up like walking or stationary cycling.
A few exercises target the most common weak links. Stretching the outer hip by crossing one leg behind the other and leaning your hip toward a wall addresses tightness in the band of tissue that runs along your outer thigh. Holding for 30 seconds and repeating four times on each side is a standard protocol. For strengthening, side-lying leg raises (hip abduction) build the gluteal muscles that stabilize the pelvis. Starting with eight repetitions and working up to twelve, then adding small amounts of weight, progressively loads the muscles that support the hip.
Beyond specific exercises, reducing aggravating activities matters. If lying on your side triggers pain, placing a pillow between your knees can reduce pressure on the outer hip. If prolonged sitting worsens groin pain, standing and moving every 30 to 45 minutes helps. Pain that doesn’t improve after six weeks of consistent home management, or that’s getting worse, is worth having evaluated with imaging and a physical exam to narrow down the specific cause.
When Surgery Enters the Picture
For hip pain caused by advanced arthritis that hasn’t responded to physical therapy, weight management, and other conservative measures, total hip replacement is one of the most successful operations in medicine. First-time hip replacements have implant survival rates well above 90% at the ten-year mark. Even revision surgeries, which are more complex, show about 85% implant survival at ten years. Most people experience dramatic pain relief and return to walking, cycling, swimming, and other low-impact activities within a few months of surgery.
For labral tears and impingement in younger patients, arthroscopic surgery can repair or reconstruct the labrum and reshape the bone to prevent further damage. Recovery typically takes three to six months, with a structured physical therapy program guiding the return to full activity. Not every labral tear needs surgery; many respond to physical therapy alone, particularly when mechanical symptoms like catching and locking are absent.
