A user friendly apparatus and method provides effective pain control resulting from headaches and facial aches, which can be safely used by patients and medical personal alike. The economical apparatus can provide a controller equipped with an injector having a tubular section and nozzle, as well as a nostril-engaging introducer and an optional handle. In the user friendly method, the tubular section of the injector can be inserted through a nostril. The nozzle can then be positioned at an upward angle of inclination in proximity and downwardly and rearwardly of the sphenopalatine ganglion (SPG nerve). Thereafter, an anesthetic can be injected through the nozzle and sprayed upwardly, towards and about the SPG nerve to minimize pain and control a headache or facial ache.
