Ilioinguinal and Iliohypogastric Nerve Entrapment: Abdominal

Ilioinguinal and iliohypogastric nerve entrapment is an under-recognized cause of abdominal and groin pain. These nerves can become entrapped after abdominal or hernia surgery and can result in disabling pain in the inguinal area or abdominal wall. The distribution and features of this pain can vary between patients, depending on anatomic variations in the course of the ilioinguinal and iliohypogastric nerves and the location of the entrapment. The pain can be diagnosed with nerve blocks and treated with neurolysis, neurectomy, or stimulation.
