If pain persists or worsens, a clinician can determine whether imaging or another form of investigation is necessary.
7. Hip Fractures: A Serious Cause of Sudden Pain
A hip fracture is a break in the upper portion of the thighbone or an adjacent area.
These injuries are particularly concerning in older adults, especially those with osteoporosis or an increased risk of falls.
A fracture may occur after a significant accident, but in people with fragile bones, even a relatively minor fall can cause serious injury.
Typical symptoms include sudden hip or groin pain, difficulty standing, and an inability to bear weight on the affected leg.
Some people notice that the leg appears shortened or turned outward, although these signs are not always present.
A person with a suspected hip fracture should not attempt to walk it off or repeatedly test the injured leg.
Severe hip pain after a fall or injury, especially when standing or walking is impossible, requires emergency medical assessment.
Prompt treatment is important because hip fractures can cause substantial complications, particularly when care is delayed.
Imaging is generally needed to confirm the diagnosis. Occasionally, additional imaging may be required if an initial X-ray does not show a fracture that remains strongly suspected.
8. Osteoporosis and Stress Fractures
Osteoporosis is a condition in which bones become less dense and more vulnerable to fractures.
It often develops without noticeable symptoms until a fracture occurs.
Although osteoporosis itself does not always cause hip pain, it can increase the likelihood of fractures involving the hip or other bones.
Stress fractures are a different but related concern. They are small cracks in bone that can develop when repetitive loading exceeds the bone's ability to repair itself.
They may occur in people who abruptly increase their exercise intensity, particularly during running or other repetitive weight-bearing activities.
Pain may begin during exercise and gradually become more persistent. In some cases, it can eventually occur during ordinary walking or even at rest.
A suspected stress fracture requires medical assessment because continuing high-impact activity can worsen the injury.
Do not assume that progressive groin pain in an active person is simply a muscle strain.
Depending on the location and severity, a clinician may recommend imaging and temporary restrictions on weight-bearing activity.
Early recognition can help prevent a minor bone injury from progressing into a more serious fracture.
9. Inflammatory Arthritis and Other Joint Conditions
Not all hip joint pain is caused by wear and tear.
Inflammatory conditions, including rheumatoid arthritis and certain forms of spondyloarthritis, can cause joint pain and stiffness.
Symptoms may include prolonged morning stiffness, discomfort after rest, reduced mobility, or pain affecting several joints.
Some inflammatory conditions can also involve the spine, tendons, or other parts of the body.
The pattern of symptoms, medical history, examination, and appropriate tests help clinicians determine whether inflammation is involved.
Other joint conditions, including disorders affecting the blood supply to the femoral head, can also cause hip pain.
One example is osteonecrosis, in which bone tissue is damaged because its blood supply is reduced or interrupted.
Risk factors vary and can include certain medical conditions, previous injuries, and particular medication exposures.
Persistent groin pain or progressive difficulty bearing weight should not automatically be attributed to osteoarthritis.
The appropriate diagnosis matters because treatment differs substantially between degenerative, inflammatory, traumatic, and other causes of hip pain.
10. When Hip Pain Could Signal an Infection
A joint infection is uncommon but potentially dangerous.
Infectious arthritis occurs when microorganisms enter a joint and cause inflammation. The hip is a deep joint, so symptoms may not always be obvious from the outside.
Warning signs can include severe pain, fever, feeling generally unwell, and substantial difficulty moving the affected hip or bearing weight.
The joint may become extremely painful with movement.
People with weakened immune systems, recent surgery, certain infections, or other risk factors may be more vulnerable, although joint infections can occur in different circumstances.
A suddenly painful hip accompanied by fever or significant illness requires urgent medical assessment.
Prompt diagnosis and treatment are important because an infection can damage the joint and spread beyond it.
Treatment may involve hospital care, tests to identify the organism, antibiotics, and drainage of infected fluid when necessary.
Do not attempt to manage a suspected joint infection with exercise, massage, or home remedies.
11. Groin Pain That Seems to Come From the Hip
The location of hip pain can provide clues about its source.
Pain in the groin or front of the hip is commonly associated with conditions affecting the hip joint, although other causes are possible.
Hip osteoarthritis, labral problems, fractures, and some tendon conditions can produce groin discomfort.
Pain in the outer hip may be more suggestive of greater trochanteric pain syndrome, while pain in the buttock may be related to the lower back or surrounding muscles.
These patterns are not absolute. Conditions can overlap, and some people experience pain in several areas.
Groin pain may also arise from structures outside the musculoskeletal system, including abdominal or pelvic conditions.
For example, a hernia can cause discomfort near the groin, particularly with lifting, coughing, or straining.
Certain abdominal or pelvic conditions can also produce pain that is mistaken for hip pain.
If the discomfort is persistent, unexplained, or accompanied by abdominal symptoms, urinary symptoms, fever, or other unusual changes, medical assessment is appropriate.
The goal is to identify the actual source rather than assuming that every pain near the hip is a joint problem.
12. Hip Pain During the Night
Pain that becomes noticeable at night can have several explanations.
A person with outer-hip tendon irritation may experience discomfort when lying on the affected side. Joint stiffness or inflammation can also make it difficult to find a comfortable sleeping position.
Muscle strains and back problems may cause symptoms that vary with posture.
However, night pain is not automatically a sign of a serious disease, and it does not identify a specific diagnosis by itself.
What matters is the overall pattern.
Pain that is persistent, progressive, unexplained, or severe enough to repeatedly interrupt sleep deserves medical assessment, particularly when accompanied by fever, unexplained weight loss, a history of cancer, or other concerning symptoms.
A clinician can determine whether the pain is likely to be musculoskeletal or whether additional investigations are needed.
For some people with outer-hip pain, avoiding pressure on the affected side and placing a pillow between the knees may improve comfort.
These adjustments can help with positioning, but they should not be used to dismiss persistent or worsening symptoms.
13. Why Hip Pain May Become More Noticeable as You Age
As people grow older, changes in muscle strength, joint structure, bone density, balance, and physical activity can influence hip health.
Osteoarthritis becomes more common with age, and some older adults experience reduced muscle mass or strength.
Balance problems and certain medications may increase the likelihood of falls.
However, aging alone does not explain every case of hip pain.
Older adults can develop muscle strains, tendon problems, fractures, nerve irritation, inflammatory conditions, and other disorders.
Maintaining appropriate physical activity can help preserve muscle strength, balance, and mobility.
Depending on the person's health and abilities, this may include walking, resistance exercise, balance training, or low-impact activities.
People with osteoporosis or a history of falls may benefit from a clinician's assessment of bone health and fall risk.
Sudden changes in mobility, persistent pain, or difficulty bearing weight should not be dismissed as an inevitable part of aging.
Early assessment can identify treatable problems and help people maintain independence for longer.
14. How Excess Body Weight Can Affect the Hips
The hips carry a substantial portion of the body's load during standing and walking.
Excess body weight can increase mechanical demands on weight-bearing joints and is associated with a higher risk of hip osteoarthritis.
However, body weight is only one factor among many. Genetics, previous injuries, joint structure, muscle function, and other medical conditions also influence hip health.
