So today, I was driving down the road in pretty thick traffic and had to hit my brakes really hard to avoid a crash. As always, with every adrenaline related incident, I got this very sudden tingly feeling all over, most notably in my neck. What is the physical cause of this? Muscles tightening, increased blood flow or something completely different?
