I had a ilioinguinal nerve block yesterday that didn't help at all, even though that is exactly where my pain is at (lower left abdomen radiating into upper inner groin). The pain dr. recommends I try a lidocaine infusion next. This is where they put an IV in your arm and then systemically administer lidocaine into your bloodstream for 30 min. She said it can help 'reset' the nervous system and calm down the painful nerve endings. Anyone had any experience with this????
