What Makes Your Foot
"Go to Sleep"?
Sometimes, after you have been sitting on your foot, you get a prickly feeling in it.
That feeling means that not enough blood has been moving through your foot. You have been squeezing the veins and arteries so that blood could barely pass through them. When this happens, your blood cannot carry waste out of your cells.
Your nerve cells become "poisoned" with waste. They are not able to send messages to your brain. Your foot feels numb, and we say it has "gone to sleep".
But when you get up and stretch your foot out again, blood suddenly starts flowing again. The nerves on your foot begin to send a lot of messages to your brain. You feel all the activity as "pins and needles" pricking your foot!!
