Title: Two tennis balls in a sock
Review: My PT recommended the tennis balls in a sock after I went through weeks of PT for neck arthritis, and still had bunched muscles and headaches. Same concept, much cheaper, and less squishy, according to the other reviews here.The spot under the skull at the top of the neck is a great place to reduce muscle tension, though, if you are suffering. Give this gizmo or the tb's a try. Good luck.
