A method is provided for suppressing or preventing pain in a patient. One step of the method includes positioning first and second electrodes, without penetrating the cranium, on or proximate to at least one of the sphenopalatine ganglia, the sphenopalatine nerves, or the vidian nerves on both sides of the patients face. At least one of a medication solution, an analgesic, or an electrical signal is then applied to at least one of the sphenopalatine ganglia, the sphenopalatine nerves, or the vidian nerves through the first and second electrodes. Pain signal generation in, or transmission through, the at least one of the sphenopalatine ganglia, sphenopalatine nerves, or vidian nerves is disrupted on both sides of the patients face.
