The feeling most patients experience during treatment is a gentle tapping on your scalp. The  tapping feeling is from the quick magnetic pulses the machine emits during the session.    Along with the feeling, you will also hear a tapping sound. Some patients may find this tapping uncomfortable at first; however, after the first few treatment sessions most patients feel most discomfort is resolved. This is due to the nerves on your scalp becoming de-sensitized to the magnetic pulse.
