Diagnosis and Management of Inguinal Nerve Entrapment Pain

Diagnostic Criteria

• The combination of burning‑type groin pain, a negative ultrasound, absence of cutaneous rash, and a history of prior inguinal hernia strongly points to inguinal nerve entrapment rather than recurrent hernia or other structural lesions. American Urological Association (AUA) 2025 guideline. Evidence level: not specified 1

• Burning pain is a hallmark of neuropathic mechanisms and helps differentiate nerve entrapment from visceral or musculoskeletal sources. AUA 2025 guideline. Evidence level: not specified 1

Physical‑Examination Priorities (AUA 2025)

• Systematic screening for neurologic and musculoskeletal abnormalities is recommended as the first step in evaluating chronic groin pain. AUA 2025 guideline. Evidence level: not specified 1

• Transrectal digital palpation of the pelvic floor (levator ani and obturator internus) can uncover tenderness that may refer pain to the groin. AUA 2025 guideline. Evidence level: not specified 1

• Examination of the hips and lumbar spine is essential to exclude referred pain from lumbosacral radiculopathy or hip joint disease. AUA 2025 guideline. Evidence level: not specified 1

First‑Line Conservative Management

• A supervised, active physical‑therapy program focused on core strengthening and neuromuscular rehabilitation for 6–12 weeks addresses pelvic‑floor dysfunction and abdominal‑wall weakness. AUA 2025 guideline. Evidence level: not specified 1

• Improving biomechanics through targeted exercises reduces irritation of the entrapped nerves. AUA 2025 guideline. Evidence level: not specified 2

• The AUA recommends initiating this regimen even when a nerve‑entrapment etiology is suspected. AUA 2025 guideline. Evidence level: not specified 1

Advanced Interventional/Surgical Options

• For patients with refractory pain, Targeted Robotic‑Assisted Intra‑Abdominal Denervation (TRAAD) can be employed to ablate the genitofemoral nerve above the internal inguinal ring in complex, treatment‑resistant cases. AUA 2025 guideline. Evidence level: not specified [2][3]

Critical Pitfalls

• A negative ultrasound does not exclude nerve pathology; nerve entrapment remains a common cause of persistent post‑hernia pain. AUA 2025 guideline. Evidence level: not specified 1

• Co‑existing lumbosacral radiculopathy and hip pathology frequently accompany groin pain and should be actively sought. AUA 2025 guideline. Evidence level: not specified 1

Expected Complications

• Potential adverse events of surgical or interventional nerve procedures include bruising, inadvertent cautery injury to adjacent nerves, and, rarely, persistent pain that may require chronic pain‑management strategies. AUA 2025 guideline. Evidence level: not specified [2][3]
