A writing instrument, such as a ball point pen, includes a vibrating relay mechanism that includes a relay arm that moves between a first position abutting a housing and a second position spaced from the housing. When the arm moves into the first position, the impact between the arm and the housing sends a shock that is transferred to the user to relieve the tension associated with writer's cramp. A control mechanism controls the cyclical operation of the vibrating relay arm, and a power source includes a battery stored in the housing.
