No. This is one of the most commonly asked questions. Each IB-Stim device is checked several times in the factory before they are shipped and activated immediately before placement. The device will be working when placed. It is normal to not feel any pulsing or sensation in the ear immediately after placement. It is also not unusual for the pulsing sensation to go away after the first day because the nerves can get used to the stimulation. Just because you don’t feel it doesn’t mean it is not working.
