Persistent numbness or weakness should also be assessed promptly, even when the pain itself is not severe.
Hip Impingement and Other Joint Problems
Femoroacetabular impingement occurs when the shape of the hip bones contributes to abnormal contact during certain movements. This may irritate the joint tissues, particularly during repeated deep hip bending or twisting.
People may notice pain in the groin, stiffness, or a feeling of pinching when squatting deeply, sitting in a low chair, or bringing the knee toward the chest. Some individuals experience clicking or catching sensations.
However, imaging may show features of impingement in people who have no symptoms. The presence of a particular bone shape does not automatically mean that it is the cause of someone's pain.
When symptoms are present, treatment may include modifying movements that repeatedly provoke discomfort, improving strength and movement control, and working with a physical therapist. Surgery may be considered in selected cases when symptoms remain significant despite appropriate nonsurgical care.
Other conditions can also affect the hip joint. Labral tears involve damage to the ring of cartilage that helps deepen the hip socket. They may cause groin pain, clicking, catching, or discomfort during rotation, although symptoms vary and these findings are not specific to labral injury.
Because several conditions produce similar symptoms, persistent pain should not be diagnosed solely from a description of clicking or pinching.
Hip Pain After a Fall or Injury
A fall, collision, or sudden impact can damage the bones and soft tissues around the hip. While a mild bruise may heal with time, some injuries require immediate medical attention.
A hip fracture is particularly important to recognize in older adults and people with weakened bones. It may occur after a significant fall, but in some individuals even a relatively minor incident can cause a fracture.
Symptoms may include severe hip or groin pain, difficulty standing, inability to walk, swelling, or bruising. The affected leg may appear shorter or turned outward, although these signs are not always present.
Anyone who experiences severe hip pain after a fall or cannot stand or bear weight should seek emergency medical assessment. Do not attempt to force the person to walk or repeatedly move the injured hip to check whether it is broken.
Some fractures, particularly stress fractures or certain fractures that have not displaced significantly, may initially cause less dramatic symptoms. A person may still be able to walk despite an injury. Persistent pain after a fall or a sudden increase in exercise should therefore be evaluated when a fracture is possible.
Stress fractures can also develop gradually when repetitive loading exceeds the bone's ability to repair itself. They are a concern among some runners, military recruits, and other people who increase impact activity rapidly. Pain may initially occur only during exercise and later become noticeable with ordinary walking or at rest.
If a stress fracture is suspected, stop impact exercise and seek medical evaluation rather than attempting to train through the pain.
When Hip Pain Is Related to Inflammation or Infection
Although many hip problems develop gradually, some conditions cause rapid, severe symptoms and require urgent treatment.
Septic arthritis is an infection inside a joint. It can damage the joint quickly and may cause severe pain, warmth, swelling, fever, and difficulty moving the affected hip. Because the hip joint lies deep beneath the surrounding tissues, visible swelling may not always be obvious.
A hot, painful joint accompanied by fever or feeling seriously unwell should be assessed urgently. Do not wait several days to see whether the symptoms disappear.
Inflammatory diseases, including certain forms of arthritis, can also cause hip discomfort. Depending on the condition, symptoms may include prolonged morning stiffness, pain in multiple joints, fatigue, or other systemic symptoms.
Inflammatory arthritis is different from ordinary age-related osteoarthritis, and the treatment approach may differ substantially.
Occasionally, hip-region pain may also originate from nearby organs or structures. Certain abdominal, pelvic, urinary, or reproductive conditions can produce pain that is felt near the hip. This is one reason why a comprehensive medical history is important, especially when pain occurs alongside abdominal symptoms, urinary changes, fever, or other unexpected signs.
Could Your Sleeping Position Be Making Hip Pain Worse?
Some people notice hip pain mainly at night or when waking in the morning. Sleeping position can contribute to discomfort, especially when the outer hip is already sensitive.
For example, lying directly on a painful outer hip can place sustained pressure on irritated tendons and nearby tissues. Sleeping on the opposite side may also cause discomfort if the upper leg falls across the body and increases tension around the affected hip.
A few simple adjustments may help:
-
If you sleep on your side, try lying on the less painful side with a pillow between your knees.
-
If you sleep on your back, consider placing a pillow beneath your knees if this feels comfortable.
-
Avoid positions that consistently produce sharp pain or numbness.
-
Choose a mattress and pillows that allow you to rest comfortably without forcing your hips into an uncomfortable position.
These adjustments may reduce pressure, but they do not treat every underlying cause of hip pain.
Pain that repeatedly wakes you from sleep, becomes progressively worse, or occurs with fever, unexplained weight loss, or a history of cancer deserves medical assessment. Nighttime pain does not automatically indicate a serious disease, but persistent symptoms should not be attributed to a mattress without considering other possibilities.
