The present invention presents an apparatus and methods to generate and deliver resonant vibrations to a hypodermic needle penetration site of a human body to reduce pain of needle prick by activating inhibitory neuronal mechanisms for pain perception. The apparatus comprises a longitudinal syringe carriage assembly which releasably holds and slidably moves a proximal portion of a syringe and a vibration assembly which generates and delivers vibrations to a vibration resonance enclosure located at a proximal end of the apparatus. The vibration assembly adjoins in parallel the syringe carriage assembly. A syringe with a needle moves forward in the syringe carriage assembly along a longitudinal axis and the needle penetrates a recipients tissue which is in direct contact with and is vibrated by the proximal end of the apparatus.
