The funny bone exists in your body, but it’s not a bone at all! The funny bone is a part of the ulnar nerve located at the back of the elbow. If you accidentally bump this area it can cause a tingling sensation toward the front of your forearm.
This tingling or dull pain is caused by the ulnar nerve bumping up against the humerus, the long bone that starts at your elbow and goes up to your shoulder. Although it might feel weird, tapping your funny bone doesn’t do any damage to your elbow, arm, or ulnar nerve.
