The main reason to switch to a different pillow is to ease neck pain (find a good shoulder pillow). Another reason to think about switching is that Cervicalgia is the cause of many more serious health issues over time. While this pain can be the result of many factors such as car crashes, sports injuries or genetics, using the wrong neck support for these pre-existing conditions only serves to exacerbate the problem by inflicting tension and stress on the neck and back.
