Ilioinguinal Nerve Block

Originating from the first low back (lumbar) spinal nerve, the ilioinguinal nerve wraps above the upper ridge of the hip bone (the iliac crest) and travels down into the groin. Its fibers are distributed to the skin and muscle, providing sensation to the groin, perineum and upper inner thigh.

What is a Ilioinguinal Nerve Block?

This minimally invasive procedure is performed by our specialist using a steroid and anti-inflammatory mixture injected into the ilioinguinal nerve that essentially blocks the pain signal, and is performed under fluoroscopy (X-ray) guidance.

What to expect during a Ilioinguinal Nerve Block procedure

Your pain specialist will have you lay on your back while they numb the surrounding skin with a local anesthetic. With fluoroscopic guidance they insert a small needle into your groin region and inject the steroid medication. The procedure takes less than 10 minutes, and you go home the same day.

What to expect after a Ilioinguinal Nerve Block procedure

Immediately after the injection, pressure is applied to the injection site to decrease the incidence of post block bruising or swelling. The patient is transferred to the recovery area for approximately 15 minutes. Patients are asked to report the percentage of pain relief and report the relief experienced during the next week by calling the clinic.
