What Causes Severe Groin Pain When Walking?

The groin is the area where the lower abdomen meets the thigh, and pain originating here can signify a range of issues from simple muscle strains to serious joint conditions. Experiencing severe groin pain when walking is particularly concerning because the act of weight-bearing and hip movement exacerbates many underlying problems. This level of pain requires immediate consultation with a healthcare professional for a precise diagnosis.

What Conditions Cause Groin Pain When Walking?

Severe groin pain during walking often originates in the mechanics of the hip joint and surrounding soft tissues. Common causes include strains or tears in the adductor muscles of the inner thigh or the hip flexors, particularly in athletes. Walking forces these muscles to stabilize the pelvis and control leg movement, causing intense pain.

Structural problems within the hip joint also cause pain, such as a hip labral tear or femoroacetabular impingement (FAI). A labral tear involves the ring of cartilage that seals the socket. FAI occurs when extra bone growth on the ball or socket creates friction and pinches tissue during movement. Both conditions cause deep, sharp groin pain, often aggravated by weight-bearing activities or prolonged sitting.

A hernia is another origin of pain, occurring when tissue, such as part of the intestine, pushes through a weak spot in the abdominal wall near the groin. An inguinal or femoral hernia causes a noticeable ache or burning sensation that intensifies with physical exertion due to increased pressure. The presence of a palpable, often reducible, bulge helps differentiate a hernia from musculoskeletal issues.

More serious conditions include avascular necrosis (AVN) of the femoral head. AVN results from a loss of blood supply to the bone tissue, causing bone cells to die and the bone surface to collapse over time. The primary symptom is a deep, persistent ache in the groin or buttock that becomes acutely painful when weight is placed on the leg during walking. Another potential cause is nerve entrapment, such as Meralgia Paresthetica, where the lateral femoral cutaneous nerve is compressed. This condition presents as a burning or tingling sensation on the outer thigh, frequently worsened by walking or standing.

The Medical Diagnostic Process

Accurately diagnosing severe groin pain begins with a detailed patient history, focusing on the onset, quality, and specific activities that worsen the pain. This is followed by a thorough physical examination, including palpating the area for tenderness, muscle asymmetry, or a hernia bulge. The clinician also performs specific movement tests to isolate the pain source, such as the FADIR (Flexion-Adduction-Internal Rotation) and FABER (Flexion-Abduction-External Rotation) maneuvers.

These provocative tests compress or stretch structures around the hip joint. Reproducing the patient’s pain can indicate a hip joint problem like FAI or a labral tear. However, physical tests are not always sufficient to confirm a diagnosis, given the close proximity of various muscle, tendon, and joint structures in the groin.

Medical imaging is frequently required to differentiate between a soft tissue injury and a bony or internal problem. Standard X-rays are often the first step, providing a clear view of the hip joint’s structure to check for FAI bone shapes, stress fractures, or signs of advanced AVN. An ultrasound examination can visualize soft tissues and confirm the presence of a fluid collection or a hernia. For detailed assessment of soft tissue damage, such as a labral tear, muscle tear, or early-stage AVN, a Magnetic Resonance Imaging (MRI) scan is the most effective tool.

Managing Groin Pain Through Treatment and Recovery

Treatment for groin pain depends entirely on the final diagnosis, with initial management focusing on conservative strategies. For acute muscle or tendon strains, the R.I.C.E. principles—Rest, Ice, Compression, and Elevation—are recommended to reduce initial pain and swelling. Nonsteroidal anti-inflammatory drugs (NSAIDs) can also manage inflammation and discomfort during the early recovery phase.

Once the initial pain subsides, physical therapy becomes a central component of recovery, focusing on strengthening the hip adductor muscles and improving core stability. Targeted exercises, such as the adductor ball squeeze or the Copenhagen plank, help restore muscle function and prevent recurrence of the injury. Recovery from a muscle strain can take anywhere from a few weeks for a minor tear to several months for a more severe Grade 2 injury.

For structural issues, the treatment path is more complex, often involving injection therapy or surgery. Corticosteroid injections can temporarily reduce inflammation and pain in cases like hip impingement or severe tendinitis. Conditions such as a painful hernia, a significant labral tear, or advanced FAI that does not respond to conservative care often require surgical intervention.

Hernias are repaired by pushing the protruding tissue back into the abdomen and reinforcing the weakened muscle wall, often with a synthetic mesh. For hip joint issues, arthroscopic surgery allows the surgeon to repair a torn labrum or reshape the bone to alleviate impingement. In the most serious cases, such as advanced AVN where the femoral head has collapsed, a total hip replacement may be the only option to provide lasting pain relief and restore walking ability.
