Whenever I am having an insomnia night, I can always feel my heart pounding in many places - the bottom of my feet, my ears, my stomach, my armpits, my eyes, my back, my throat, everywhere! If you try to reposition yourself, sometimes it helps. Try not to think about it (yeah, right) and it will start to go away also. Just remember that we are very sensitive to our physical symptoms and the more we pay attention to whatever symptom it may be at that time, the worse it will seem. But, this doesn't make it more dangerous - just more noticeable.
