Hip pain during walking usually comes from one of a handful of common problems: arthritis wearing down the joint, a structural issue with the bones or cartilage, a muscle strain, or pain referred from the lower back. The specific location of the pain, when it hits during your stride, and how it feels all point toward different causes.
Osteoarthritis: The Most Common Cause
Osteoarthritis is the leading reason adults develop hip pain while walking, especially after age 50. The cartilage that cushions the ball-and-socket joint gradually breaks down, leaving bone surfaces to grind against each other with every step. This creates a deep, aching pain that tends to build over the course of a walk rather than hitting all at once.
People with hip arthritis typically walk with less hip extension, meaning the leg doesn’t swing as far behind the body during the push-off phase of each step. Research published in Frontiers in Sports and Active Living found that this shift toward a more flexed, guarded walking pattern actually begins before arthritis fully develops, appearing in people with early-stage hip disease. Interestingly, these gait changes persist even after hip replacement surgery, suggesting the body learns a protective movement pattern and keeps it long after the original source of pain is addressed.
The pain from hip arthritis is often assumed to stay in the groin area, but that’s not always the case. A study of 60 patients awaiting hip replacement found that 47% experienced pain that traveled below the knee. This overlap makes it easy to confuse hip arthritis with a knee problem or a nerve issue in the lower back.
Labral Tears
The labrum is a ring of tough cartilage that lines the rim of the hip socket, helping to seal the joint and keep the ball of the femur stable. When it tears, you may feel a catching, clicking, or locking sensation during walking, especially when changing direction or pivoting. The pain often settles deep in the groin and can feel sharp with certain movements, then dull at rest.
Labral tears can develop from repetitive motion, a single traumatic event, or structural abnormalities in the hip bones. They’re common in runners and athletes who do a lot of twisting, but they also affect people with no athletic history. Because the labrum has limited blood supply, small tears don’t always heal on their own.
Femoroacetabular Impingement (FAI)
Sometimes the hip bones themselves are shaped in a way that creates problems. Femoroacetabular impingement occurs when extra bone along the rim of the socket or the head of the thighbone causes the two surfaces to rub, catch, or pinch against each other during movement. Walking may not always be the worst trigger (squatting, lunging, and climbing stairs often provoke more pain), but longer walks or faster paces can bring it on.
FAI pain typically radiates into the groin, buttock, or thigh. Over time, the repeated friction can damage the labrum and accelerate cartilage loss, making impingement both a standalone cause of pain and a contributor to future arthritis. Many people with FAI don’t realize they have it until the cumulative damage starts producing symptoms during everyday activities like walking.
Hip Flexor Strain
The hip flexors are a group of muscles at the front of the hip that lift your knee toward your body with every step. When these muscles are strained, walking often produces a pulling or cramping sensation in the front of the hip or upper thigh. Climbing stairs and walking on slopes tend to be especially uncomfortable. A moderate strain can make it difficult to walk without limping.
Hip flexor problems are common in people who sit for long hours and then shift to activity. Prolonged sitting shortens these muscles, and when you stand up and walk, the tight, shortened fibers are forced to lengthen and contract repeatedly. This combination of tightness and sudden demand is a recipe for strain, particularly if you’ve recently increased your walking distance or pace.
Bursitis
Bursae are small fluid-filled sacs that reduce friction between bones, tendons, and muscles around the hip. When a bursa becomes inflamed (bursitis), the pain tends to settle on the outer side of the hip, right over the bony prominence you can feel when you press. Walking aggravates it because each stride compresses the inflamed tissue. The pain is often worse when lying on the affected side at night, which distinguishes it from many other hip conditions.
Trochanteric bursitis, the most common type at the hip, frequently develops from repetitive stress: walking on hard surfaces, suddenly increasing mileage, or running with poor form. It can also flare after a fall directly onto the hip.
Pain Referred From the Lower Back
Not all hip pain actually starts in the hip. Compressed or irritated nerves in the lower spine can send pain signals down into the hip, buttock, and leg. This referred pain can convincingly mimic a hip joint problem, and the two conditions coexist often enough to make diagnosis tricky. One key difference: nerve-related pain from the spine often includes tingling, numbness, or a burning quality that true hip joint pain doesn’t produce. It may also follow a line down the back or side of the leg rather than concentrating in the groin.
The sacroiliac (SI) joint, where the spine meets the pelvis, is another source of referred hip pain. SI joint dysfunction tends to cause a deep, one-sided ache in the buttock that worsens with walking and standing. Because the hip joint, lumbar spine, and SI joint all share overlapping nerve pathways, pinpointing the real source sometimes requires a diagnostic injection that temporarily numbs one structure to see if the pain disappears.
How Location Helps Narrow the Cause
Where you feel the pain is one of the most useful clues:
- Groin or deep front of the hip: Most likely the hip joint itself, including arthritis, labral tears, or impingement.
- Outer hip: Bursitis or irritation of the tendons that attach to the outer thighbone.
- Front of the hip or upper thigh: Hip flexor strain or, less commonly, a nerve issue from the upper lumbar spine.
- Buttock or back of the hip: Often referred from the lower back, SI joint, or piriformis muscle.
These patterns aren’t absolute. Hip arthritis alone can produce pain in the groin, thigh, buttock, and even below the knee. But they give you a starting framework for understanding what might be going on before you see a provider.
What Helps and What to Watch For
Staying active is important regardless of the cause. Resting completely tends to weaken the muscles that support the hip and can make pain worse over time. The goal is to keep moving while avoiding the specific motions or intensities that provoke sharp pain.
Shortening your stride length takes pressure off the hip joint during walking. If you normally take long steps, consciously bringing your feet closer together reduces how far the hip has to extend behind you, which is the phase of walking most affected by arthritis and impingement. Walking on flat, even surfaces rather than hills also lowers the demand on the hip flexors and joint.
Strengthening the muscles around the hip, particularly the glutes and the deep stabilizers on the outer hip, helps distribute load away from the joint itself. Even simple exercises like side-lying leg lifts and bridges can make a meaningful difference over several weeks. Stretching the hip flexors after prolonged sitting, before they’re asked to work through a full walking stride, reduces the risk of strain.
Pain that persists for more than a few weeks, wakes you at night, or causes a noticeable limp warrants evaluation. A physical exam that moves the hip through specific positions can identify the likely source with reasonable accuracy. For impingement, one common test (flexing, abducting, and externally rotating the hip) has a sensitivity above 96%, meaning it catches nearly all cases. Imaging may follow if the exam suggests a structural problem that conservative treatment won’t resolve.
