1. A method comprising: applying transcutaneous electrical neurostimulation to multiple stimulation regions on an epidermal surface adjacent a neuralgic region of a patient; selecting one of the stimulation regions based on perceived efficacy of the transcutaneous electrical neurostimulation in the selected stimulation region; applying percutaneous electrical neurostimulation to multiple stimulation sites within the selected stimulation region; and selecting one of the stimulation sites based on perceived efficacy of the percutaneous electrical neurostimulation in the selected stimulation site.
