This device helps reduce painful tension which accumulates at the back of the head and neck. It works through the controlled use of pressure at specific tension or trigger points. The specially crafted triangular design has three edges, graded from blunt to more penetrating, in order to apply the appropriate amount of pressure to your neck. The Neck Relaxer is used daily for brief periods of time and is helpful for headaches, stiff necks, insomnia, and neck and shoulder tension.
