We've all felt it. You hit your elbow, and that numbness sears it all over. Today however, I leaned back in my chair, and hit my elbow with very little force. But I hit my funny bone at such a precise point that my entire forearm from elbow to the tip of my pinky finger went numb for around half a minute. Are there any techniques to exploit this specific glitch in the human body? Thanks for taking your time on this thread.
