Final answer:
Symptoms of Iliohypogastric nerve entrapment include lower abdominal, groin, and pelvic pain, potential numbness in the same areas, and sometimes muscle weakness in the lower abdominal wall.
Step-by-step explanation:
Nerve Entrapment Syndrome of the Iliohypogastric nerve (T12-L1) would likely involve symptoms such as sharp or aching pain in the lower abdomen, groin, and pelvic area; possible loss of sensation or numbness in these regions; and difficulty with certain movements that stretch the affected nerve. In some cases, there might also be muscle weakness in the lower abdominal wall. Considering that the iliohypogastric nerve arises from the first lumbar nerve (L1) with contributions from the twelfth thoracic nerve (T12), its entrapment can also mimic conditions like appendicitis, UTIs, and PID, but without the full range of symptoms associated with those disorders.
