Severe right hip pain usually comes from one of a handful of common conditions, and where exactly you feel the pain is the single best clue to what’s causing it. Pain in the front of the hip points to problems inside the joint itself. Pain on the outer side often involves the tendons and fluid-filled sacs around the bony point of the hip. Pain in the back or deep in the buttock frequently traces back to the spine, the sacroiliac joint, or compressed nerves. Understanding which pattern matches yours can help you figure out what’s going on and what to do next.
Where You Feel It Matters Most
Hip pain isn’t one-size-fits-all. The hip is a deep ball-and-socket joint surrounded by layers of muscle, tendon, and bursae (small cushioning sacs), and pain can originate from inside the joint, from the soft tissues around it, or from somewhere else entirely. Doctors typically sort hip pain into three zones: anterior (front/groin), lateral (outer side), and posterior (back/buttock). Each zone has its own shortlist of likely causes.
Front-of-hip pain that settles deep in the groin usually signals something happening inside the joint: cartilage damage, a torn labrum, impingement from abnormal bone shape, or arthritis. Lateral pain, right over the bony bump you can feel on the outside of your hip, is more commonly a soft tissue problem like bursitis or a tendon issue. Posterior pain that wraps into your buttock or shoots down your leg often originates in the lower back or the sacroiliac joint rather than the hip itself.
Outer Hip Pain: Bursitis and Tendon Problems
The most common cause of pain on the outside of the hip is greater trochanteric pain syndrome, an umbrella term that covers bursitis, tendon irritation or tears in the gluteal muscles, and friction from the iliotibial band. If your pain is right at the bony point of the hip and spreads across the outer thigh, this is a likely culprit.
In its early stages, trochanteric bursitis feels sharp and intense, localized to that bony point. Over time it often evolves into a broader ache that covers a larger area. The hallmark pattern is pain that gets worse at night (especially when lying on the affected side), when standing up after sitting for a while, and during prolonged walking, stair climbing, or squatting. If you’ve noticed that rolling onto your right side in bed wakes you up, bursitis is high on the list.
This condition is especially common in women over 40, runners, and people who have recently increased their walking or stair use. It often responds well to rest, ice, stretching, and physical therapy focused on strengthening the gluteal muscles.
Groin Pain: Labral Tears and Impingement
Deep groin pain with a catching or locking sensation usually points to a problem inside the hip joint. Two of the most common are labral tears and femoroacetabular impingement (FAI), and they frequently go hand in hand.
The labrum is a ring of cartilage that lines the rim of your hip socket, helping to keep the ball of the thigh bone stable. When it tears, you may feel a sharp catch deep in the groin when you pivot, twist, or get out of a low chair. Stiffness, a limited range of motion, and a feeling of instability in the hip are also typical. The pain often flares with athletic activity and can be hard to pinpoint because it sits so deep.
FAI happens when the bones of the hip joint aren’t perfectly shaped, creating extra friction during movement. In one form, extra bone grows on the top of the thigh bone. In another, the socket itself has a bony overgrowth. Either way, the result is painful pinching or rubbing inside the joint that makes it hard to move freely. You might feel stiff or sore on one side all the time, with sharper pain when you bring your knee up toward your chest or rotate the leg inward. Over years, untreated impingement can damage the labrum and accelerate arthritis.
Hip Arthritis
Osteoarthritis is the most common form of arthritis in the hip and a leading reason for severe, persistent hip pain in adults over 50. The cartilage that cushions the joint gradually wears down, leaving bone grinding closer to bone. Pain typically starts as stiffness in the morning or after sitting, then progresses to aching during walking and eventually pain at rest or at night.
The progression is gradual. Early on, you might only notice it after a long walk or a day on your feet. As the joint space narrows further, everyday tasks like bending to tie your shoes, getting in and out of a car, or climbing stairs become painful. When hip pain limits your daily activities, persists while resting, and no longer responds to anti-inflammatory medications or physical therapy, that’s typically when hip replacement surgery enters the conversation.
When the Problem Is Your Back, Not Your Hip
One of the most overlooked causes of right hip pain is referred pain from the lower back. A herniated disc or narrowed nerve channel in the lumbar spine can compress a nerve root, sending pain, numbness, or tingling down into the hip, buttock, and leg. This is called lumbar radiculopathy, and it can mimic hip joint problems convincingly.
The giveaway is usually the pain pattern. Referred pain from the spine tends to travel: it may start in the lower back or buttock and radiate down the back or side of the thigh, sometimes reaching the knee or foot. Sitting for long periods, especially in a car, can make it worse. If your “hip” pain comes with tingling, numbness, or a burning quality that follows a line down your leg, the source is more likely a pinched nerve in your spine than a problem inside the hip joint.
Deep gluteal syndrome is a related condition where nerves in the buttock get compressed by surrounding muscles or other structures. It causes deep buttock pain that worsens with sitting and can produce sciatica, a burning pain that shoots down the leg. There’s often no clear injury. It develops gradually.
Nerve Entrapment on the Outer Thigh
A separate nerve issue called meralgia paresthetica causes tingling, burning pain, or numbness specifically on the outer part of the thigh. It happens when a sensory nerve running through the groin gets compressed, often by tight clothing, weight gain, or prolonged standing. The symptoms typically affect one side and get worse after walking or standing. This condition doesn’t involve the hip joint at all, but people frequently describe it as hip pain because of where they feel it.
Posterior Hip and Buttock Pain
Pain in the back of the hip or deep in the buttock has its own set of causes beyond referred spine pain. Sacroiliac joint dysfunction, where the joint connecting the base of the spine to the pelvis becomes inflamed or moves abnormally, is a common one. It tends to cause one-sided pain in the low back and buttock that worsens with standing, walking, or climbing stairs.
Ischiofemoral impingement causes deep buttock pain that worsens with activities requiring a long stride, like running or fast walking. Proximal hamstring tendinopathy, an overuse injury of the tendons at the top of the hamstring where they attach to the sitting bone, produces pain in the lower buttock that flares with activities involving hip extension, like lunging or sprinting.
Signs That Need Urgent Attention
Most hip pain develops gradually and responds to conservative treatment. But certain patterns require prompt medical evaluation. Septic arthritis, an infection inside the joint, causes bad pain that comes on fast, along with swelling, warmth, skin color changes over the joint, and often a fever. If severe hip pain appeared suddenly and you feel unwell, that combination warrants same-day medical care. Fast treatment helps prevent permanent joint damage.
A stress fracture of the femoral neck, more common in distance runners and older adults with thinning bones, causes groin pain that worsens with weight-bearing activity and may hurt even at rest. Avascular necrosis, where blood supply to the ball of the thigh bone is disrupted, produces a similar pattern that worsens progressively over weeks to months. Both conditions can worsen significantly without treatment.
If your right hip pain came on suddenly without injury, is severe enough that you can’t bear weight, is accompanied by fever, or has been steadily worsening over several weeks despite rest, those are all reasons to get it evaluated sooner rather than later. An X-ray, physical exam, and sometimes an MRI can usually distinguish between the various possibilities and point you toward the right treatment.
