The present disclosure relates to an apparatus and associated methods to produce analgesia in a mammal by providing an electrical nerve stimulus utilizing a pulsed input of low level electrical current, wherein the level of current is measurable with the measurements utilized to at least adjust the strength of the current according to selected parameters. Additionally, the use of magnets to produce a magnetic field to further control chronic and acute pain. In exemplary implementations, the apparatus maintains continuous monitoring of the electrical characteristics of TENS at the site of input and output, and the electrical input can be modified during treatment to obtain desired electrical input. More particularly the disclosure relates to an electromagnetic apparatus incorporating pulsed direct current, two or more electrodes, and at least two dipole antennas wherein the dipole antenna circuits receive and analyze signal from the dipole antennas, using the information from signal analysis within the methods for producing analgesia in mammals. The strength of the current that the patient is receiving at the targeted site as the actual field is measured by the dipole antennas and adjustment is not dependent on subjective measurements to ascertain whether the proper amplitude, frequency and pulse duration are being applied.
