A device for safely relieving pain in a human or animal includes a pair of pads for placing against a body at spaced apart locations, e.g. on the front and back of an abdomen for treating back pain. One of the pads has an electrically conductive layer, e.g. aluminum foil for placing against the body where treatment is required, and the other pad includes an electrically conductive core sandwiched between insulating layers. The electrically conductive layer and the core are connected to the electrodes of a dry cell or other source of direct current, whereby a direct current is caused to flow between the body and the electrically conducting layer.
