A pain controlling device includes a pair of housings, each having a jaw at one end and a handle at the other end. The jaws, which are held together a resilient coupling connecting the housings, may be separated by squeezing the handles together. Each of the housings includes a source of mechanical vibration that can be turned on to control pain in an extremity that is clamped between the jaws, such as in a finger from which a blood sample is to be taken.
