An auricular peripheral nerve field stimulator includes at least one therapy electrode configured for percutaneous insertion into an auricle of a human ear near at least one neurovascular bundle, and an electrical stimulation device electrically coupled to the at least one therapy electrode, the electrical stimulation device programmed to (i) generate and deliver electrical stimulation signals to the inserted at least one therapy electrode at a selected frequency for a selected duration to stimulate at least one auricular peripheral nerve field within the auricle, and (ii) repeat (i) with the stimulation signals having a modulated frequency.
