A hip that’s going bad typically announces itself with pain in the groin, not on the side of the hip where most people expect it. That groin pain is present in about 84% of people with hip joint problems, making it the single most reliable signal that something is wrong inside the joint itself. But hip issues can show up in surprising ways, including knee pain, a limp you can’t seem to correct, or stiffness that makes everyday tasks like tying your shoes feel impossible.
Where Hip Pain Actually Shows Up
The location of your pain says a lot about what’s going on. True hip joint problems, like arthritis or a torn labrum, typically cause a deep ache in the groin or the front of the thigh. Many people describe it as feeling like the pain is coming from deep inside, not on the surface. Buttock pain is also common with hip joint degeneration.
What surprises most people is how far the pain can travel. Nearly half of people with hip arthritis report pain below the knee, often along the inner thigh and down toward the inner calf. This happens because the hip joint shares nerve pathways with the leg, so a deteriorating hip can mimic knee problems. It’s not unusual for someone to spend months treating a “bad knee” before discovering the real issue is the hip.
Pain on the outer side of the hip, right over the bony point you can feel when you press, is a different story. That’s more characteristic of bursitis, an inflammation of the fluid-filled cushions around the joint rather than the joint itself. Bursitis pain tends to be sharp and focused, and it flares when you lie on that side or climb stairs. Hip joint pain, by contrast, is usually a deeper, duller ache that worsens with activity and eases with rest, at least in the earlier stages.
Stiffness and Lost Range of Motion
Morning stiffness is one of the hallmark signs of a hip going bad. With hip arthritis, you’ll typically feel stiff and slow when you first get out of bed, but it loosens up within about an hour. If your stiffness lasts significantly longer than that, it may point to an inflammatory condition rather than standard wear-and-tear arthritis.
As the hip deteriorates, you start losing the ability to move your leg in certain directions. Internal rotation, the motion of turning your leg inward, is usually the first to go. A healthy hip can rotate inward about 30 degrees or more. People with hip impingement or labral tears often have internal rotation reduced to around 10 degrees, sometimes less. You might notice this as difficulty crossing your legs, getting in and out of a car, or reaching down to put on socks and shoes. If one hip rotates noticeably less than the other, with a difference greater than 15 degrees, that’s a strong indicator of a joint problem on the restricted side.
Clicking, Catching, and Giving Way
Mechanical symptoms point to structural damage inside the joint, most commonly a labral tear. The labrum is a ring of cartilage that lines the rim of the hip socket, and when it tears, it can get pinched between the ball and socket during movement. This produces clicking, a catching sensation, or moments where the hip feels like it’s about to give out.
Clicking is the most consistent symptom of a labral tear. Some people describe it as a clunk they can feel deep in the joint during specific movements, like swinging a leg over a bicycle or pivoting. Locking, where the hip briefly feels stuck, is less common but more alarming when it happens. These mechanical symptoms often occur alongside groin pain, especially with activities that involve twisting or deep bending at the hip.
Changes in How You Walk
A bad hip changes your gait, sometimes so gradually you don’t notice it yourself. One telltale pattern is a limp where your trunk leans toward the affected side with each step. This happens because the muscles on the outside of your hip, which normally keep your pelvis level when you lift the opposite foot, have weakened or can’t fire properly due to pain. The result is that your pelvis drops on the opposite side during walking, producing a visible lurch or waddle.
People with a limp are about seven times more likely to have a hip problem than a spine problem alone. If friends or family have commented on changes in your walking, or you notice you’re covering less distance than you used to before pain stops you, those are meaningful signals worth paying attention to.
How Hip Pain Differs From Back Pain
Hip problems and lower back problems can produce overlapping symptoms, which is why they’re frequently confused. Both can cause pain in the buttock, thigh, and even the knee. But a few markers help sort them out.
Groin pain strongly favors a hip problem. People with groin pain are seven times more likely to have a hip disorder than a spine disorder alone. Similarly, reduced internal rotation of the hip makes a hip problem 14 times more likely than a pure back issue. Back-related pain, by contrast, tends to radiate in a stripe down the back or side of the leg, often past the knee and into the foot, and it frequently worsens with bending or sitting rather than with weight-bearing activities like walking.
If your pain is mainly in the groin, gets worse when you walk or stand, and your hip feels stiff when you try to rotate it, the hip joint is the more likely source. If the pain shoots down the back of your leg and changes with your spinal position, your lower back deserves closer attention. Some people have both, which makes sorting it out trickier.
How Symptoms Progress Over Time
Hip problems rarely arrive all at once. In the early stages, you might feel an ache after a long walk or a hard workout that goes away with rest. Some conditions, like avascular necrosis (where blood supply to the bone is disrupted), produce no symptoms at all in their earliest phase.
As the condition advances, pain starts showing up with routine weight-bearing activities: walking across a parking lot, standing up from a chair, going up stairs. The threshold for triggering pain drops steadily. Eventually, the pain can become constant, present even when you’re lying down or trying to sleep. This progression from activity-related pain to resting pain is a signal that the joint is worsening and often marks the point where people start seriously considering their treatment options.
Along the way, you may notice you’ve unconsciously adjusted your life around the hip. You avoid stairs, you stopped taking walks, you sit down to put on pants. These functional losses accumulate slowly, and recognizing them as symptoms rather than just “getting older” is important.
Signs That Need Urgent Attention
Most hip problems develop gradually, but a few scenarios call for immediate medical evaluation. A hip that suddenly becomes painful and swollen alongside a fever could indicate a joint infection, which can cause serious damage if not treated quickly. Complete inability to bear weight after a fall, especially in older adults, raises concern for a fracture. Sudden, severe groin pain without an obvious injury can also signal avascular necrosis or, rarely, other conditions that need prompt assessment.
