Surgery, infection or trauma can cause damage to the ilioinguinal nerve. This causes pain in the groin area and/or inner thigh. The ilioinguinal nerve originates from the first lower back spinal nerve and wraps above the iliac crest and travels into the groin. This nerve provides sensation to the upper inner thigh, groin, and perineum. For pain relief, we can provide Ilioinguinal nerve block at our office.
