The brain, spinal cord, and nerves are all a part of the central nervous system, which is responsible for transmitting information to the different parts of the body. With fibromyalgia, the brain sometimes sends “itch” signals to the nerves in the skin, which can later on form a rash. This can also make it overly sensitive, which triggers a feeling of itchiness or a crawling sensation on the surface or the skin. And if you already happen to have dry skin, it can even make the itching and rash worse.
