A wall-mounted back massager adapted to allow a user to self-administer a massage is disclosed. The inventive wall-mounted back massager comprises: an elongated wall mount track vertically positioned on a wall; a vertically adjustable elongated base member slidably engaged to the wall mount track; a plurality of swivel head assemblies attached in series along the elongated base member; and at least first and second pairs of spaced apart and axially aligned wheels rotatably attached to each of the plurality of swivel head assemblies by respective first and second wheel axles. Each swivel head assembly is pivotably between first and second swivel head positions. In this configuration, vertical movement of a person's back due to bending and straightening of their knees effects movement of the swivel head assemblies and attached wheels relative to the person's back, thereby allowing the person to enjoy a self-administered massage.
