Sometimes nausea is a byproduct of vertigo. Slight misalignments of your vertebrae, called subluxations, can cause dizziness. The reason is that there are balance receptors on your spine. When the information coming from your eyes and inner ear does not match the information from the receptors on your spinal cord, a wave of nausea can result. Before reaching for pharmaceuticals, see a chiropractor. One adjustment may be all you need to make the world stop spinning.
