What happens when you bang your elbow and your funny bone 'activates' and what is that tingling sensation?
Name: Hazel, Hammersmith
Answer: When you hit that small area on your elbow, you are hitting the ulnar nerve against the end of the humerus. The ulnar nerve that supplies feeling to the little finger and ring feeling, gives you this the funny feeling.
