Johns Hopkins University Researchers Scratch the Surface of the Science Behind Itchiness

Scientists have only just begun to scratch the surface of the mystery of why we itch. For example, Medical Daily recently reported on a recent study that explained part of why itching is contagious. However, why does only our skin become itchy? Is itchiness a form of pain? Why does just reading about itchiness make you itchy? A recent study published in Nature Neuroscience sought to answer two of those three questions.
