What Causes Tingling When You Hit Your Funny Bone?

Subjects > Health
THAT feeling you get when you knock your elbow is caused by the ulnar nerve that runs the length of the arm. It carries signals from the hand to the brain, but can be triggered by a bang on the elbow. Then the brain gets a message that you've hurt your arm and combined with the twang on the nerve - which causes temporary paralysis - it can make you laugh.

WHAT YOU CAN DO: Enjoy the laughter.

WHEN TO WORRY: "If a strange sensation continues for over an hour or the elbow area swells up, you may have a small fracture or torn ligament, so get it checked out," says Dr Vandenburg.
