There's something called reflexology. It says that all body functions are somehow connected to the feet. I do know that when I can't sleep I rub my feet and it relaxes me every time. There are times that I have knots here or there on my foot that are very tender. Rubbing those spots help me feel better. Hope this "bumping" will help get you a better answer. Maybe googling might give you an answer.
