What are symptoms of nerve entrapment/injury after inguinal hernia surgery. and if exist how to detect that one is nerve entrapment?

Clinical : Sharp/burning/lancinating pain traveling from the incision to the pubic area, scrotum, or thigh, tingling sensation in these area, pain with stretching, coughing/sneezing, pain relief w/ local anesthetic injection are usually diagnostic. Imaging study (e.g. Mri, us) is rarely needed. Symptoms may occur soon after surgery, or months to years later. Neurectomy has a 90% cure rate.

Pain and tingling: Pain, numbness, and tingling, are the typical symptoms associated with nerve entrapment after inguinal hernia repair. Diagnosis is typically made with a careful history and physical examination. A nerve block can also help diagnose the problem as well as the potential response to treatment options. Seeing a specialist with an interest in peripheral neuropathy may help. These typically include anesthesiologists or plastic surgeons.
