An electrosurgical generator that can be used, for example, to provide radio-frequency (RF) energy for localized tissue coagulation, cutting, ablation, and to create lesions in nervous tissue. The generator can provide controls for line power, RF power, setting temperature and/or power, for selecting preset temperature and power combinations, and for selecting programmed treatment profiles. The generator can have a display to display the desired probe and tissue temperature, measured probe impedance, actual probe and/or tissue temperature, delivered power, treatment time, mode setting, preset selection, and messages, and indicators for RF Power On, Stimulation On, and Fault Condition. The generator can include the ability to generate low frequency pulses to stimulate nerves and to assist in the proper placement of the electrosurgical probe in the location that is causing pain.
