RUNNERS ITCH. Quote:When we are too busy to hit the gym capillaries collapse and there is a decrease in blood flow. When we get ourselves moving again and get to the gym or out for a run these capillaries begin to expand because of our rapid heart beat and faster blood flow. As these capillaries begin to expand it causes nearby nerves to send signals to the brain. Our brain interprets these signals as the need to itch AnaphylaxisQuote:If you notice additional symptoms while running, you may have a more serious condition known as exercise-induced anaphylaxis. In addition to the itching, runners with this condition might also experience difficulty breathing, vomiting and fainting. If you continue running despite these symptoms, the condition might block the flow of oxygen to your heart and brain, resulting in death.  For some people, the condition is triggered simply by vigorous exercise walkathon.
