Hip Pain

Hip pain is a common problem that can affect people of all ages. It may start as a dull ache after activity or appear suddenly with sharp discomfort. Injuries, arthritis, bursitis, and other joint or muscle conditions often cause hip pain.

Understanding why the hip hurts is the first step toward finding relief. Pain can come from inside the joint, such as cartilage wear, or from tissues around the joint, like tendons and muscles. Sometimes, pain that feels like it’s from the hip actually comes from the back or knees, making it harder to identify the true source.

Because hip pain can signal different issues, from minor strains to more serious conditions, it helps to know what symptoms to watch for and when to seek help. Paying attention to the type and location of pain can guide the next steps in care and help prevent long-term problems.

Definition of Symptom

Hip pain means discomfort felt in or around the hip joint, which connects the pelvis to the thigh bone. This pain can be sharp, dull, or aching, and it may spread to nearby areas like the thigh, buttock, or groin.

In adults, hip pain often signals irritation or injury to structures such as the hip labrum, hip flexor muscles, or surrounding ligaments. It may also reflect changes in the cartilage or bone that limit smooth movement of the joint.

The symptom can appear during daily activities such as walking, climbing stairs, or sitting for long periods. Some people notice pain when lying on the affected side or when rotating the leg. Common features of hip pain include:

  • Localized soreness in the hip joint.
  • Groin pain that worsens with activity.
  • Stiffness or reduced range of motion.
  • Swelling or tenderness around the joint.

A simple way to understand the symptom is to note where the pain is felt:

Location of PainPossible Source
GroinHip joint, labrum, or flexors
Outer hipTendons, bursae, or muscles
ButtockPelvis or referred pain from spine

Possible Causes

Hip pain can start with problems in the bones, cartilage, muscles, or soft tissues around the joint. Some conditions last only a short time, while others may cause long-lasting discomfort or joint damage.

  • Arthritis is a leading cause. Osteoarthritis gradually wears down cartilage, while rheumatoid arthritis and other types of inflammatory arthritis happen when the immune system targets the joint. These conditions often cause stiffness, swelling, and reduced movement.
  • Bursitis develops when small fluid-filled sacs called bursae become irritated. Trochanteric bursitis affects the outer hip and often causes pain when lying on the side. Repeated stress or injury can trigger this condition.
  • Injuries and fractures can also cause hip pain. A hip fracture or stress fracture can happen after a fall or from weakened bones. Hip injuries may also include muscle strains, cartilage tears, or labral tears, which can cause sharp pain during movement.
  • Structural problems like femoroacetabular impingement (FAI) and hip dysplasia limit normal joint motion. These issues can lead to cartilage damage over time and increase the risk of arthritis.
  • Other conditions include snapping hip syndrome, where tendons move over bone and create a snapping sound, and sciatica, where nerve irritation causes pain that radiates into the hip.

Some serious causes include osteonecrosis, where poor blood flow damages bone tissue, and joint infections, which need urgent care.

Other Non-Disease Causes

Hip pain does not always come from disease or long-term conditions. Everyday activities and lifestyle factors can also play a role. These causes are often temporary and may improve with rest or simple care.

  • Overuse and Strain: Repetitive movements from sports, exercise, or heavy lifting can strain the muscles and tendons around the hip. This may lead to soreness or stiffness that eases with rest, stretching, or light activity changes.
  • Injury from Activity: Falls, sudden twists, or direct impact can cause bruising or mild sprains without underlying disease.
  • Poor Posture and Sitting Habits: Long hours of sitting, especially with poor posture, can place stress on the hip joints.
  • Improper Footwear: Shoes that lack support can affect walking patterns and place extra pressure on the hips.

How It Causes the Symptom

Irritation, swelling, or damage to the structures in or around the hip joint cause pain. Because the hip is a ball-and-socket joint, even small changes in cartilage, bone, or soft tissue can create discomfort. Common ways pain develops include:

  • Cartilage breakdown in arthritis reduces cushioning, causing bones to rub together.
  • Swelling in bursitis or tendonitis irritates tissues and makes movement painful.
  • Injury or fracture disrupts bone stability and produces sharp pain.

A torn labrum, the ring of cartilage around the hip socket, can cause clicking, stiffness, or limited motion. Strains or overuse injuries can also cause swelling and soreness in surrounding muscles and tendons.

Some conditions get worse over time. Osteoarthritis or ongoing joint damage may eventually require hip replacement surgery. This procedure restores function by replacing worn surfaces with artificial parts.

In less severe cases, doctors can use hip arthroscopy to repair cartilage tears or remove loose fragments. More complex injuries may need open surgery to fix bone or soft tissue. Pain often feels different depending on the cause. For example:

CauseHow It Creates Pain
ArthritisCartilage loss leads to bone friction.
BursitisInflamed fluid sacs press on tissues.
FractureBroken bone disrupts joint stability.
Labral tearDamaged cartilage limits smooth motion.

Each of these changes affects how the hip joint moves, which explains why pain can feel sharp, dull, or burning depending on the source.

Possible Complications

Hip pain can lead to more than discomfort if not managed properly. Some people may develop reduced mobility, making it harder to walk, climb stairs, or perform daily tasks. Over time, this limited movement can weaken surrounding muscles. In certain cases, untreated hip pain may cause joint stiffness and loss of range of motion. This can affect balance and increase the risk of falls, especially in older adults.

More serious conditions, such as fractures or infections, may result in long-term joint damage. If arthritis is the cause, the cartilage breakdown can worsen, leading to chronic pain and possible need for surgery. Common complications include:

  • Persistent pain that interferes with sleep.
  • Swelling and soreness around the joint.
  • Difficulty bearing weight on the affected hip.
  • Reduced independence in daily activities.
ComplicationPossible Outcome
Chronic stiffnessLimited mobility, reduced activity
Untreated arthritisJoint damage, need for replacement
Hip fractureSurgery, long recovery
Recurrent bursitisOngoing pain, reduced flexibility

When to Seek Medical Attention

Hip pain sometimes gets better with rest, ice, or over-the-counter medicine. But ongoing or severe pain may signal a more serious problem that needs medical care. Seek urgent help if you notice:

  • A hip joint that looks deformed or out of place.
  • A leg that appears shorter than the other.
  • Sudden, severe pain after a fall or injury.
  • You cannot put weight on the hip or leg.
  • Intense swelling, redness, or warmth around the joint.

If hip pain lasts more than two weeks, keeps you from sleeping, or limits daily activities, make an appointment with a doctor. In many cases, your primary care provider may send you to an orthopedist for further evaluation. An orthopedist can check the joint, order imaging tests, and suggest treatment options to keep the problem from getting worse. For quick reference:
