A device for delivery of TENS current or electrostimulation has a first skin contact electrode mounted on a first non-conductive fingertip base and having at least one contact area for current-bearing contact with skin and a connection to a TENS current source and has a second skin contact electrode, mounted on a non-conductive fingertip base that is the same as the first non-conductive fingertip base or is a second non-conductive fingertip base and having at least one contact area for current-bearing contact with skin and a connection to TENS current source. A control and power unit that supplies TENS current to flow through skin contacting and positioned between the first and second electrodes, and enables selecting the level of the current or energy supplied.
