A device that relieves pain in a region of a user's body by contacting an electrode with a surface of the user's body in that region and providing a continuous electrical impulse in that region, the device comprising: A signal generator comprising: at least two electrodes adapted to contact a surface of the user's body; (b) a control unit; and (c) a signal generator associated with and responsive to the control unit. And the control unit is adapted to operably connect to the power supply, and the signal generator is adapted to provide a continuous electrical impulse to the body surface via the electrodes in the operating mode. Includes a plurality of cycles, each of which includes a positive voltage pulse and a negative voltage pulse, the frequency of the plurality of cycles is optionally between 60 and 150 per second The time-average voltage amplitude (Vap) of the positive voltage pulse within the range of the cycle is 20 to 90 volts throughout the whole period (Tpossitive), and the rising portion of the positive voltage pulse is (1) Achieving at least 80% of the time-averaged voltage amplitude within a time period of 70-150 nanoseconds (T80), and (2) the positive voltage pulse is increased by at least 20 volts within 70 nanoseconds. Satisfy at least one of the conditions. [Selection] Figure 5B
