Ilioinguinal Nerve, Iliohypogastric Nerve, Genitofemoral Nerve Block

The ilioinguinal, iliohypogastric and genitofemoral nerves supply sensation to parts of the lower abdomen, groin, upper inner thigh and genital region. Irritation of these nerves can contribute to persistent groin or lower abdominal pain, including pain following abdominal or groin surgery, hernia repair or other local injury.

A nerve block involves placing a fine needle close to the relevant nerve or nerves and injecting local anaesthetic, with or without corticosteroid. Ultrasound guidance is commonly used to identify the nerves and surrounding anatomy, particularly because their course can vary between individuals. One or more nerves may be targeted depending on the distribution of your pain.

The block may provide temporary pain relief and can help determine whether one of these nerves is a significant contributor to your symptoms. A good but short-lived response may support further treatment, including pulsed radiofrequency in selected patients. Dr Danesh will assess your pain pattern and response before recommending any subsequent procedure.
