5 Common Reasons for Hip Pain and What They Might Mean

Hip pain can start in different ways. It may build slowly over months, or hit after a long walk, hard workout, or awkward twist. Some people notice it in the groin. Others notice it on the outside of the hip, in the buttocks, or even in the knee. That is one reason the symptom can be hard to read without context. According to Mayo Clinic, “The location of the pain can offer clues about the cause.” Pain in the groin often points closer to the joint itself. Pain on the outside often points to muscles, tendons, or bursae around it. Hip pain can also originate from the lower back or pelvis rather than the hip alone.

That wide range matters because the same symptom can describe very different problems. Penn Medicine lists joint disease, labral tears, impingement, tendon issues, bursitis, fractures, and arthritis as possible sources of pain. Mayo Clinic also notes that arthritis, injuries, and other conditions can all be responsible. The clearest clues come from location, triggers, stiffness after rest, and red flags like swelling, fever, or a recent fall. Here are 5 common reasons hips hurt, along with what each one may mean.

Osteoarthritis and other forms of arthritis

Arthritis is among the most common causes of persistent hip pain, particularly in midlife and older age. The hip is a weight-bearing joint, so worn cartilage can quickly affect walking, stairs, sleep, and basic daily movement. The American Academy of Orthopaedic Surgeons states, “Osteoarthritis develops slowly, and the pain it causes worsens over time.” People often notice groin pain first. The pain can also radiate to the buttock, inner thigh, or knee. Morning stiffness, or stiffness after sitting, is another common clue. The NHS reports that osteoarthritis becomes more likely after 45 and that pain is often worse when walking. NIAMS also notes that hip arthritis can limit the range of motion and make standing or climbing more difficult. Many people first notice small losses. 

Shoes become harder to tie. Getting out of a car becomes awkward. A short walk begins to produce a deep ache that was not there before. AAOS explains that osteoarthritis of the hip causes pain and stiffness and can make everyday tasks difficult. This cause ranks higher on the list when the pain is daily, mechanical, and associated with movement after periods of rest. What it might mean depends on the pattern. If the pain builds over months, stiffens after rest, and eases a bit once you get moving, joint wear becomes more likely. Osteoarthritis happens when cartilage and related tissues break down over time, according to NIAMS. AAOS reports that prior hip injury, obesity, age, and abnormal hip formation can all increase the risk. 

Arthritis is not always osteoarthritis, though. Mayo Clinic lists rheumatoid arthritis, psoriatic arthritis, juvenile idiopathic arthritis, and septic arthritis among possible causes of hip pain. AAOS also notes that inflammatory arthritis can affect the hip. It may show up earlier in life because an overactive immune system drives it. That distinction matters in practice. A hot, swollen joint with fever or chills requires urgent care because infection can rapidly damage the joint. Pain with prolonged morning stiffness, swelling, and symptoms in other joints may suggest inflammatory disease rather than wear alone. Doctors use the history, physical examination, and sometimes imaging or blood tests to sort out those causes. Management also varies by cause. AAOS says there is no cure for osteoarthritis, yet many treatments can help people manage pain and stay active. 

Those steps often include exercise, weight management, pain relief, and, in more advanced cases, joint replacement. That means a sore hip does not automatically point to surgery. It may indicate a joint that requires support, improved loading, and a clear diagnosis before the damage becomes more difficult to manage. Another clue is duration. Arthritis usually hangs around. It may flare, yet it rarely behaves like a brief muscle pull. Some people also notice reduced internal rotation long before severe pain arrives. By the time sleep, stairs, and short walks are affected, the joint often requires a more comprehensive assessment and a more structured treatment plan. Over time, untreated stiffness can reduce confidence in movement, which often leads people to avoid activity and lose further strength.

Bursitis and tendon irritation on the outside of the hip

Pain on the outside of the hip often points away from serious joint damage and toward irritated soft tissue. Two common culprits are bursitis and tendonitis. A bursa is a fluid-filled sac that helps tissues glide over bone. When it becomes inflamed, the hip may become tender and sore. AAOS notes that trochanteric bursitis typically causes pain at the hip. That pain can spread down the outer thigh. It often gets worse at night, when lying on the sore side, or after getting up from a chair. Rush orthopedic surgeon Shane Nho, MD, says, “It just hurts day to day.” That helps distinguish bursitis from pain that occurs only during sport or strenuous exercise. 

Mayo Clinic also notes that outer hip pain often links to muscles, tendons, ligaments, or bursae surrounding the joint. In plain terms, pain in this area often signals that the tissues around the hip are overloaded or inflamed, even if the joint surface itself is still fine. Tendon irritation can look similar, yet the trigger is often different. Rush explains that hip flexor or groin tenderness in active individuals may indicate tendinitis, which can follow repetitive movement. Shane Nho says, “People who do very specific activities over and over” can drive that severe pain. AAOS adds that overuse, long-standing, stair climbing, cycling, running, tight tissue, leg-length differences, and spine problems can contribute. This pattern may indicate that the problem lies in the tissue around the hip, rather than deep within the socket. 

The pain may flare with pressure, repeated movement, or certain sleeping positions. Doctors often look for tenderness over the bony outer hip. They may order X-rays or an MRI to rule out other problems. Treatment often starts with relative rest, ice, anti-inflammatory medication, and targeted exercise, yet persistent pain still deserves a proper exam. If the pain recurs, the underlying cause may be gait changes, weak hip muscles, or another condition that has been overlooked. Pain that appears when you lie on that side, stand after sitting, or climb stairs often fits this picture. Bursitis becomes more common with age, and AAOS says it is more common in women and in middle-aged or older adults. 

That does not mean younger adults are spared, but it does help explain why outer hip pain becomes more common later in life. When the diagnosis is correct, treatment can be very focused because the source sits close to the surface and responds to load changes. It also helps explain why some people can point to one exact tender spot with a fingertip. Deep arthritis pain is often harder to pin down. Outer hip bursitis usually is not. That contrast can help patients describe their pain more clearly during an appointment. It can also help a clinician decide early whether the joint itself is likely involved. That can shorten the path to proper treatment. Gentle strengthening of the gluteal muscles can improve hip stability, reduce friction around the joint, and lower the risk of flare-ups.

Not all hip pain begins inside the joint. Sometimes the source is a strained muscle or tendon that supports the hip and pelvis. AAOS states, “A hip strain occurs when one of the muscles supporting the hip joint is stretched beyond its limit or is torn.” These injuries can happen during sports. They can also occur during routine activities. The risk rises with sudden stretching, a fall, direct impact, or repeated movement that slowly irritates the tissue. Rush notes that core muscle injuries and sports hernias often cause groin pain. They are common among individuals who engage in twisting sports without adequate conditioning. AAOS adds that the lower abdominal muscles and hip flexor muscles are often involved. That helps explain why the pain can seem confusing at first. 

It may sit in the front of the hip, yet the true source is in a nearby muscle or tendon. The NHS lists strains, sprains, and tendonitis among common causes of pain, swelling, or bruising after intense or repetitive exercise. That history is often one of the strongest clues. It may indicate overuse, poor load management, or a new strain that needs time to settle. Pain that started after sprinting, kicking, lunging, heavy lifting, or a sudden slip tells a different story from pain that crept in over the years. AAOS explains that severe strains can limit movement and that injured muscles become more vulnerable to reinjury. It also notes that hip strains can be mild, moderate, or severe, depending on the extent of tissue damage. 

Mild strains may improve with home care, but major tears, loss of function, or recurring pain often need medical review and guided rehabilitation. MedlinePlus advises urgent help after a serious injury if you cannot move the hip or bear weight. That is an important dividing line. Simple soreness after exercise is one thing. Sharp pain, visible bruising, weakness, or trouble walking is another. Recovery often begins with rest from the aggravating movement, followed by careful strengthening and gradual return. If a person rushes back too soon, the same tissue may tear again, turning a short setback into a long problem. These injuries also tend to behave differently from arthritis. They are often easier to link to a single event or training block. 

The pain is usually sharper initially, then subsides if the tissue is protected. AAOS notes that many strains improve with simple home care, but severe strains may require physical therapy or other interventions. That is useful guidance for active individuals who assume that groin pain will resolve on its own. Sometimes it will. Sometimes it requires structured rehabilitation before the hip can tolerate speed, rotation, or heavy loading again. Good rehab also looks at the bigger picture. Weak core control, poor warm-up habits, and sudden spikes in training can all keep the same area irritated. When those drivers are corrected, recovery is usually more reliable, and repeat injuries are less likely. Warm-ups, gradual training increases, and adequate recovery days can protect the hip muscles from overload and reduce the risk of strains.

Hip impingement or a labral tear deep in the joint

Deep groin pain with clicking, catching, locking, or pinching during movement may indicate a structural problem within the joint. Two linked causes stand out here: femoroacetabular impingement, called FAI, and labral tears. Penn Medicine explains, “Hip impingement causes friction and abnormal wear and tear on the joint.” AAOS states that FAI occurs when extra bone alters the shape of the ball, the socket, or both. Then the bones no longer fit together cleanly. Over time, that repeated rubbing can damage nearby tissue and limit movement. Penn also notes common signs. These include groin pain during or after activity, trouble climbing stairs, limping, stiffness, and pain after long sitting. Those clues often point to a joint problem, not a sore muscle on the outside of the hip. 

This is one reason younger, active adults can still have clinically significant joint disease. Penn reports that impingement is often observed in active adults. Rush says intense athletics can contribute to abnormal bone shape and restricted movement in some younger patients. The labrum is the ring of cartilage around the socket, and it helps maintain joint stability. Mayo Clinic says trauma, repetitive pivoting, structural hip problems, and FAI can all lead to labral tears. Rush reports that labral tears often cause hip or groin pain, as well as locking, catching, or clicking. Shane Nho says, “The pain tends not to go away.” This pattern may indicate that the joint is being pinched or that the cartilage ring is damaged. People who run long distances, dance, pivot in sports, or were born with hip shape differences may be at higher risk. 

Penn adds that untreated impingement can lead to osteoarthritis and, in some cases, eventual hip replacement. Doctors, therefore, look closely at movement, pain location, and range of motion. They confirm the image when needed. Early assessment does not always mean surgery. Penn notes that physical therapy is often part of treatment. Arthroscopy may be used when symptoms persist and structural correction is needed. This cause becomes more likely when pain sits deep in the groin. It often worsens with hip flexion, long sitting, squatting, or hard training. Penn also notes trouble bending the hip beyond a right angle and loss of balance in some patients. 

Those details help separate impingement from a simple outer hip irritation. The longer the joint continues to pinch, the greater the likelihood that cartilage and the labrum will sustain further damage. That is why repeated catching, clicking, or locking warrants proper evaluation rather than guesswork. People often try to stretch through this type of pain for months. That can delay the right diagnosis. If the hip repeatedly pinches during squats, long drives, or seated work, clinicians should consider shape, joint mechanics, and labral stress. The pattern is often deeper, more mechanical, and harder to ignore once it has settled in. That is why long-standing groin pain with clicking should not be dismissed as simple post-workout soreness. Ignoring persistent catching sensations can lead to increased joint irritation, making routine movement more difficult and increasing the need for specialist assessment.

Fracture, infection, or pain that is coming from somewhere else

Some causes of hip pain are less about wear or overuse and more about urgency. A hip fracture is one of the clearest examples. MedlinePlus says hip fractures can cause sudden, acute hip pain and can lead to major problems. Mayo Clinic adds that about half of the people who sustain a hip fracture do not regain independent living. The NHS advises seeking emergency care if severe hip pain follows a fall or injury, especially if you cannot walk or bear weight on the leg. Fracture risk also rises with weaker bone. Mayo notes that lack of regular weight-bearing exercise, tobacco, and alcohol can contribute to weakening bones and muscles over time. Infection belongs in the urgent category, too. Mayo Clinic lists septic arthritis among possible causes of hip pain, and the NHS warns that a hot, swollen hip with fever, chills, or feeling unwell needs urgent assessment.

These patterns suggest something more serious than a pulled muscle after a workout. They point to a problem that can worsen quickly if treatment is delayed. Yet not every alarming hip pain starts in the hip joint itself. Mayo Clinic notes that pain on the outside often relates to soft tissue, while pain on the inside or in the groin more often points to the joint. It also states that hip pain can come from the lower back as referred pain. MedlinePlus similarly states that you may experience hip pain in the groin, thigh, or knee, and notes that some pain attributed to the hip may originate in the back. Rush adds another useful reminder through Shane Nho, MD: “The pelvis contains many systems.” 

This pattern may indicate that spinal problems, pelvic floor issues, gynecological conditions, or other adjacent structures can mimic hip disease. If the pain does not match the exam findings, shifts location, or presents with symptoms outside the joint, the search should be widened. The broader lesson is simple. Hip pain is common, but context matters. A daily ache with stiffness points in one direction. Sudden pain after a fall points to another. Night pain in the outer hip suggests a particular type of tissue. A catching groin pain suggests another. The more precise the pattern, the more quickly the correct diagnosis usually becomes apparent. 

Referred pain is a big reason people get confused. MedlinePlus states that true hip pain may present in the groin, thigh, or knee, and Mayo states that back problems can refer pain to the hip area. So a person may focus on the point of pain while the real problem sits elsewhere. That is why clinicians ask about fever, injury, limping, bruising, back pain, bowel or bladder symptoms, and even the timing of pain during daily life. Those details help sort a strained tendon from a joint infection, or a spinal problem from a hip joint disorder. They also help identify the people who should not wait and watch at home. When hip pain changes suddenly, spreads, or is accompanied by fever, weakness, or numbness, medical evaluation becomes far more important.
