Hip pain may begin inside the hip joint, around the outer hip, in nearby muscles and tendons, or in the lower back and spinal nerves. When pain travels into the thigh, knee, calf, or foot, the source may not always be the hip joint itself. Research estimates that hip pain affects approximately 10% of the general population, when one major study found that 14.3% of adults aged 60 and older experienced significant hip pain. Symptoms can interfere with walking, climbing stairs, sleeping, driving, working, exercising, and completing routine household activities.

Dr. Rao K. Ali, a Board Certified Interventional Pain Management Specialist, evaluates the complete pain pattern and looks beyond the area where pain is felt. The direction in which pain travels, accompanying numbness or weakness, and activities that worsen symptoms can help distinguish a hip-joint disorder from an inflamed bursa, tendon injury, sacroiliac joint problem, or compressed spinal nerve.

Why Does Hip Pain Travel Down the Leg?

Hip pain that radiates down the leg most commonly occurs when a nerve in the lower spine becomes irritated, inflammation around the hip refers to pain into the thigh, or a hip-joint condition sends pain toward the knee. Possible causes include:

• Sciatica

• Lumbar herniated disc

• Lumbar spinal stenosis

• Hip osteoarthritis

• Greater trochanteric pain syndrome

• Hip bursitis

• Gluteal tendon irritation

• Sacroiliac joint dysfunction

• Meralgia paresthetica

• Hip labral tears

• Muscle or tendon injuries

Common Causes of Hip Pain that Radiates Down the Leg

Hip pain that travels down the leg can develop from several different problems involving the hip joint, spine, nerves, muscles, or tendons. Below are the most common causes that may explain this type of radiating pain.

1. Sciatica and Lumbar Disc Herniation

Sciatica describes pain caused by irritation or compression of a nerve root in the lower spine. A herniated disc can press against a nearby spinal nerve, producing sharp, burning, electric, or shooting pain that begins in the lower back, buttock, or hip and travels down one leg. Other symptoms may include:

• Tingling or pins-and-needles sensations

• Numbness in the leg or foot

• Leg or foot weakness

• Pain while sitting or bending

• Pain that worsens with coughing or sneezing

2. Lumbar Spinal Stenosis

Lumbar spinal stenosis develops when the space around nerves in the lower spine narrows, placing pressure on them. It may cause back or hip pain, leg aching, heaviness, numbness, or weakness. Symptoms often worsen with standing or walking and improve with sitting or leaning forward. It is commonly linked to age-related spinal changes.

3. Hip Osteoarthritis

Hip osteoarthritis occurs when the cartilage protecting the hip joint wears down over time. It may cause groin pain, stiffness, limited movement, and difficulty walking, bending, standing up, or putting on shoes. The pain can also spread into the buttock, front of the thigh, or knee, making it feel like a leg problem. Additional symptoms can include:

• Morning stiffness

• Limping

• Grinding or catching sensations

• Pain after physical activity

• Reduced hip movement

4. Greater Trochanteric Pain Syndrome

Greater trochanteric pain syndrome affects the outer part of the hip. It may involve an inflamed bursa, irritated gluteal tendons, or a combination of both. The pain generally begins over the bony point on the side of the hip and may extend down the outside of the thigh. It can become worse when:

• Lying on the painful side

• Climbing stairs

• Walking long distances

• Standing on one leg

• Rising from a chair

• Pressing directly over the outer hip

5. Piriformis or Deep Gluteal Syndrome

The sciatic nerve passes near the piriformis muscle in the deep buttock. Muscle tightness, inflammation, or spasm may irritate the nerve and cause pain that travels down the leg. Symptoms can worsen with sitting, running, climbing stairs, or hip rotation. An examination may also assess the lower spine, sacroiliac joint, and hip.

6. Sacroiliac Joint Dysfunction

The sacroiliac joints connect the pelvis to the lower spine. Irritation or abnormal movement in one of these joints may produce pain in the lower back, buttock, hip, groin, or upper thigh. Sacroiliac joint pain may worsen when:

• Climbing stairs

• Taking long strides

• Standing unevenly

• Turning in bed

• Getting out of a chair

• Entering or leaving a vehicle

7. Meralgia Paresthetica

Meralgia paresthetica occurs when the lateral femoral cutaneous nerve is compressed near the groin, causing burning, tingling, numbness, or sensitivity along the outer thigh. Tight clothing, weight gain, pregnancy, diabetes, or injury may contribute. The best pain doctor in Dallas can identify the cause and recommend treatment when symptoms become worse when standing or walking.

8. Hip Labral Tear or Femoroacetabular Impingement

The hip labrum is a ring of cartilage surrounding the hip socket. A tear may cause deep groin pain, clicking, catching, stiffness, or instability. Femoroacetabular impingement occurs when the hip bones rub abnormally, damaging cartilage. Twisting, squatting, prolonged sitting, or sports may trigger sharp pain that can spread into the thigh.

9. Muscle or Tendon Injuries

Injuries affecting the hip flexors, gluteal muscles, hamstrings, or inner-thigh muscles can cause pain that spreads from the hip or buttock into the leg. A sudden strain may cause sharp pain, swelling, bruising, or weakness. Repetitive activity may produce a slower, persistent ache. Running, lifting, sports, workplace activities, and insufficient warm-up can increase stress on these tissues.

How Is Radiating Hip Pain Diagnosed?

An evaluation usually begins with questions about where the pain starts, how far it travels, what activities trigger it, and if numbness, weakness, stiffness, clicking, fever, or a recent injury is present. The physical examination may assess:

• Walking and balance

• Hip range of motion

• Lower-back movement

• Muscle strength

• Reflexes

• Skin sensation

• Movements that reproduce pain

Treatment for Hip Pain that Radiates Down the Leg

Treatment depends on the underlying cause, symptom severity, and its effect on daily activities. Hip pain treatment in Dallas may include activity modification, heat or ice, medication, and physical therapy. The goal is to reduce pain, improve movement, and address the source of the condition. A rehabilitation program may focus on:

• Hip mobility

• Core stability

• Posture improvement

• Gluteal muscle strength

• Gentle stretching

• Gradual return to activity

When Should You See a Pain Management Specialist?

You should consult a pain management specialist in Dallas when hip pain continues, repeatedly returns, or begins to interfere with your movement, sleep, work, or daily routine. A specialist can identify if the pain is coming from the hip joint, lower spine, nerves, muscles, or surrounding tissues and recommend the appropriate treatment.  Schedule an evaluation when the pain:

• Continues for more than a few weeks

• Repeatedly returns

• Extends below the knee

• Interrupts sleep

• Limits walking or working

• Causes numbness or tingling

• Produces leg weakness

• Becomes steadily worse

• Does not improve with home care

Conclusion

Determining what causes hip pain that radiates down the leg requires more than identifying where the pain is felt. The actual source may be the hip joint, an inflamed bursa, an injured tendon, the sacroiliac joint, or a nerve compressed in the lower spine.

The direction of the pain and the presence of stiffness, numbness, tingling, or weakness can help narrow the possible cause. Persistent, recurring, or worsening symptoms deserve an evaluation. An accurate diagnosis allows treatment to target the correct structure and helps patients avoid inappropriate exercises, medications, or injections.
