Persistent hip pain almost always points to one of a handful of common conditions, and where exactly you feel the pain is the single biggest clue to what’s going on. Pain in the front of the hip (often felt in the groin) suggests a problem inside the joint itself. Pain on the outer side of the hip points to soft tissue around the joint. And pain that wraps into the buttock or shoots down the leg may not be coming from the hip at all, but from your lower back. Understanding which pattern fits yours can help you make sense of what’s happening and what to do about it.
Front or Groin Pain: Problems Inside the Joint
If you feel a deep ache in your groin or the front of your thigh, especially when you sit for a while or try to bend forward, the most likely culprits are osteoarthritis, a labral tear, or a structural issue called femoroacetabular impingement.
Osteoarthritis is the most common cause of anterior hip pain in people over 50. The cartilage cushioning the ball-and-socket joint gradually wears down, and the exposed bones may develop small bony growths at their edges. Early on, you might notice stiffness in the morning or after sitting that loosens up with movement. Over time the pain creeps into more of your day, including rest and nighttime. You may hear or feel a grinding sensation when you move the hip, and your range of motion slowly shrinks, sometimes enough to cause a limp. Rainy or damp weather can make it flare. X-rays typically show a narrowed joint space and those bony growths.
In younger adults, femoroacetabular impingement is one of the most common sources of chronic hip pain. It happens when extra bone along the rim of the socket or the top of the thighbone causes the two surfaces to pinch against each other during movement. It tends to come on gradually with no specific injury, and it’s especially bothersome during activities that require deep bending or wide rotation of the hip.
Labral tears involve the ring of cartilage that lines the edge of the hip socket. They often result from a sports injury or repetitive motion, and they produce a distinctive clicking, popping, or catching feeling when you move the hip. The pain is usually in the front of the hip and may feel sharp during certain movements, then settle into a dull ache afterward. Activities like dance, gymnastics, hockey, and soccer are frequent triggers.
Outer Hip Pain: Soft Tissue Problems
If the pain is on the outside of your hip, worse when you walk, climb stairs, or lie on that side at night, you’re most likely dealing with greater trochanteric pain syndrome. This used to be called simply “bursitis,” but research now shows that the problem often involves damage to the tendons of the gluteal muscles that attach at the bony point on the outside of your hip, not just an inflamed bursa. It affects roughly 1.8 per 1,000 people each year and is most common in women between 40 and 60.
The pain typically develops without a clear injury. Rising from a chair, standing for a long time, and rotating the hip all tend to aggravate it. Night pain is especially common because lying on the affected side compresses those irritated tendons directly. In more advanced cases involving a full-thickness tear of the gluteal tendon, you may notice real weakness when trying to lift your leg to the side, and your gait can become visibly uneven.
Buttock or Leg Pain: Your Back May Be the Source
One of the most overlooked explanations for constant “hip” pain is that it’s actually referred from the lumbar spine. The major nerves serving the hip, thigh, and groin all originate in the lower back, so a herniated disc or pinched nerve there can produce pain you feel deep in the buttock, groin, thigh, or even down to the knee. This overlap is common enough that doctors have a name for the diagnostic challenge: hip-spine syndrome.
A key distinguishing feature is the quality of the pain. Tingling, burning, or electric-shock sensations are more consistent with a nerve issue from the spine than with a joint problem. You may also notice numbness or a strip of altered sensation running down your leg in a specific pattern. If your hip pain changes when you arch or round your lower back rather than when you move the hip itself, that’s another sign the spine deserves attention.
Deep gluteal syndrome (sometimes called piriformis syndrome) is a related cause. It involves the sciatic nerve getting compressed by muscles deep in the buttock. The hallmark is deep buttock pain that worsens with sitting and produces sciatica-like burning or shooting sensations down the leg.
Why the Pain Becomes Constant
Most of these conditions start as occasional discomfort, so if yours now feels relentless, something has likely progressed. With osteoarthritis, the cartilage loss reaches a point where bone contacts bone during everyday activities, not just strenuous ones. With tendon problems on the outer hip, ongoing irritation can shift from simple inflammation to actual structural breakdown of the tendon fibers, which heals much more slowly. And with spinal issues, a disc that was only slightly bulging may have worsened enough to press on a nerve root continuously.
Compensatory movement patterns also play a role. When one structure hurts, you unconsciously shift your weight and change how you walk. That altered gait puts abnormal stress on other muscles and joints, creating secondary pain sources that layer on top of the original problem. This is one reason chronic hip pain can feel diffuse and hard to pin down.
What Helps: Strengthening and Sleep Position
Regardless of the specific diagnosis, strengthening the gluteal muscles is one of the most consistently helpful interventions for chronic hip pain. The gluteus medius, in particular, stabilizes the pelvis every time you take a step. When it’s weak, the hip joint and surrounding tendons absorb forces they aren’t designed to handle. Exercises like single-leg bridges, side-lying leg raises, and squats with a focus on driving through the glutes all target this muscle. The key form cue is making sure the movement comes from squeezing the glute rather than letting the knee cave inward, which shifts the load away from where you need it.
Sleep positioning matters more than most people realize. If you sleep on your side, your top leg naturally falls forward and tilts the pelvis, compressing soft tissues in the hip and spine. This position is sometimes called “provocative side lying” because it actively disrupts alignment. Placing a firm pillow between your knees lifts the top leg enough to neutralize the pelvis and prevent twisting. Pairing that with a thick pillow under your head keeps the upper spine aligned as well. If your pain is from greater trochanteric pain syndrome, simply switching to the other side or to your back can cut night pain dramatically.
Steroid Injections and Their Limits
Corticosteroid injections into the hip joint or the trochanteric bursa are a common next step when exercises alone aren’t enough. They typically reduce pain and swelling for about two months, sometimes longer for chronic conditions. But they don’t fix the underlying problem. For tendon-related pain on the outer hip, injections that fail to provide lasting relief may actually be a sign that the issue is a structural tendon tear rather than simple bursitis, and further imaging may be warranted. The number of injections you can safely receive in a given area is limited, so they’re best thought of as a window of reduced pain that lets you do the strengthening work more effectively.
Patterns Worth Paying Attention To
Tracking a few details about your pain can make a real difference in getting the right diagnosis. Note where you feel it most (groin, outer hip, buttock, thigh), what makes it worse (sitting, walking, lying on it, bending), and whether it comes with any mechanical symptoms like clicking or catching. Groin pain with stiffness after sitting points toward the joint. Outer hip pain that flares at night points toward the tendons. Burning or tingling that follows a line down the leg points toward the spine. Many people have more than one of these issues at the same time, which is why persistent hip pain can feel so confusing, but even a rough sense of the pattern gives you and your provider a much better starting point.
