A massage apparatus has a spherical-shaped body and a plurality of knuckle-shaped nodes protruding from a surface of the body for myofascial release of tissue adhesions, scar tissue, and trigger points. The protruding nodes are arranged in parallel rows and located on one hemispherical face of the sphere. The nodes vary in height along a row. The rows are preferably spaced sufficient to enable effective rolling of the sphere along a spinous process of the user and without coming into contact with the vertebrae of the user.
