Why Your Hip Pain Won’t Go Away: A Complete Guide to Causes, Diagnosis, Treatment & the Best Shoes for 2026

Osteoarthritis of the hip is a progressive condition in which the articular cartilage that cushions the ball-and-socket joint wears down over time. As cartilage degrades, bone rubs against bone, causing pain, stiffness, and reduced range of motion. OA is the leading reason for hip replacement surgery in the United States, with more than 450,000 total hip arthroplasties performed annually as of 2025.

Early signs include groin pain (often felt deep in the fold where the leg meets the pelvis), stiffness after sitting for long periods, and pain that worsens with weight-bearing activities like walking or climbing stairs.

GTPS is an umbrella term for pain over the greater trochanter — the bony prominence on the outer side of the femur. It typically involves the gluteal tendons (gluteus medius and minimus) and the bursa that sits between them. GTPS is especially common in women in their 40s–60s, with rates 2–3 times higher than in men, likely due to differences in pelvic width and biomechanics.

The hallmark symptom is lateral hip pain that worsens when lying on the affected side, walking uphill, or standing on one leg. Many people report sharp pain when rolling over in bed at night.

FAI occurs when extra bone forms along the femoral head and/or the acetabulum (the socket), causing abnormal contact during hip flexion and rotation. There are three types: Cam (femoral head deformity), Pincer (over-coverage of the socket), and mixed. FAI is a major driver of hip pain in athletes and active adults aged 20–45 and is strongly associated with the development of early hip osteoarthritis if left unmanaged.

Pain is typically felt in the groin and is provoked by deep hip flexion — think squatting, lunging, or sitting in low chairs. A positive “FADIR test” (flexion, adduction, internal rotation) during a physical exam is a classic clinical sign.

It’s estimated that 20–30% of people presenting with “hip pain” actually have a spinal or sacroiliac (SI) joint source. Pain from the lumbar spine (e.g., due to facet joint arthritis, disc pathology, or nerve root compression) can radiate into the gluteal region and lateral hip. SI joint dysfunction often causes pain in the posterior hip that can be mistaken for hip joint pathology.

Key clues: pain that is more central (over the sacrum or lower back) rather than deep in the groin, pain that changes with different sitting positions, and pain that doesn’t reproduce with direct hip range-of-motion testing.

The acetabular labrum is a ring of fibrocartilage that deepens the hip socket and provides stability. Tears can occur from trauma, repetitive twisting, or as a consequence of FAI. Labral tears are increasingly diagnosed with MRI arthrography and are a common finding in athletes in sports that involve pivoting — soccer, hockey, and golf.

Symptoms include a deep, sharp groin pain, a catching or clicking sensation in the hip, and pain with prolonged sitting or rotational movements. Not all labral tears are symptomatic; incidental tears on MRI are common in asymptomatic individuals.

Bursae are small, fluid-filled sacs that reduce friction between bones and soft tissues. The two most relevant to hip pain are the trochanteric bursa (on the outer hip) and the iliopsoas bursa (deep in the front of the hip). Bursitis typically results from overuse, repetitive friction, or direct trauma.

Iliopsoas bursitis causes deep anterior groin pain, especially when extending the hip from a flexed position (like standing up from a chair). Trochanteric bursitis presents as lateral hip pain that is tender to touch and worse with pressure.

Avascular necrosis (also called osteonecrosis) occurs when blood flow to the femoral head is disrupted, leading to bone cell death and eventual collapse of the femoral head. Major risk factors include corticosteroid use, heavy alcohol consumption, sickle cell disease, and trauma (such as a hip fracture or dislocation). AVN can cause rapid-onset, severe hip pain and often leads to total hip replacement in younger patients.

Early detection is critical: MRI is the gold standard for diagnosis, as X-rays often appear normal in the early stages. If you have risk factors and develop persistent groin pain, insist on an MRI.

Sleeping on your back with a pillow under your knees reduces pressure on the hip joint. If you sleep on your side, lie on the unaffected side and place a firm pillow between your legs to keep the pelvis aligned — this prevents the top leg from dropping into adduction and straining the lateral hip structures. Avoid sleeping directly on the painful side.

Absolutely. The hip, knee, and ankle are mechanically linked. A limp or altered gait from hip pain can overload the knee (especially the medial compartment) and change foot strike patterns. It’s common for patients with undiagnosed hip OA to present with “knee pain” that actually originates from the hip — a phenomenon called referred pain or secondary overload.

With appropriate conservative care — including activity modification, PT, and possibly a corticosteroid injection — most cases of trochanteric bursitis resolve within 4–8 weeks. However, chronic cases that involve underlying gluteal tendinopathy can take 3–6 months or longer. Consistent rehabilitation that addresses both the bursitis and the underlying tendon weakness is essential to prevent recurrence.

Walking is generally good for most causes of hip pain — it maintains joint mobility, strengthens supporting muscles, and promotes cartilage health. The key is to walk with good form, on supportive surfaces, and in appropriate shoes. Start with short, frequent walks (10–15 minutes) and build gradually. If pain worsens during or immediately after walking, shorten your duration or consult a physical therapist for gait retraining. Walking through sharp, persistent pain is never advisable.

You should see an orthopedic specialist or a physical therapist if: (1) pain persists for more than 2 weeks despite basic self-care (rest, ice, over-the-counter anti-inflammatories), (2) you have trouble bearing weight or walking normally, (3) you experience night pain or pain at rest, or (4) you have a history of cancer, steroid use, or recent trauma. Early specialist evaluation can prevent small problems from becoming chronic or irreversible.

Yes — though it’s rare, a deep vein thrombosis (DVT) in the thigh or pelvis can present with hip or groin pain. Red flags for DVT include swelling, warmth, redness, and a palpable cord-like vein in the leg. If you have risk factors (recent surgery, prolonged immobility, cancer, pregnancy, or a clotting disorder) and develop these symptoms, seek emergency medical care. DVT is a medical emergency due to the risk of pulmonary embolism.
