An improved self-massage apparatus may feature a main mounting bar serving as a body and one or two coaxial and slidable tubes to provide mounting tension. An outer surface may present a rotatable massage head. The two ends of the apparatus may have brackets or other interfaces to secure the apparatus between two parallel surfaces. Clamps, ratchets, and other tension devices may be used to hold the main components in fixed relation to each other and the massage head may rotate a full 360° on at least two planes for a customizable and extremely versatile massage experience.
