Maybe once, twice, or even often, your elbows accidentally hit a hard object. Besides pain, what else do you feel? Most people complain of tingling sensations such as numbness for a moment, rather than pain just after the elbow hits a hard object.
Elbow is traversed by the ulnar nerve
All the sensations that arise when the elbow is knocked out actually are not from the elbow bone, but because there is an ulnar nerve in it. The ulnar nerve is a nerve that runs along the shoulder to the tip of the little finger. Its function as a regulator of muscles that facilitate the movement of fingers, hands, and lower arm muscles.
Unlike other nerves in the body, not all parts of the ulnar nerve are protected by muscles or bones. The ulnar nerve located in the elbow area is only covered with skin and fat.
Electric shock when the elbow hits, why?
The ulnar nerve at the elbow is located behind the humerus bone, which is the bone that stretches from the elbow to the shoulder. Unfortunately, there is a part of the ulnar nerve that is not covered by bones and muscles. Well, the open part without protection is very sensitive.
That’s why when your elbows accidentally hit, the ulnar nerve in the elbow area will send signals to the brain quickly. The brain also responds to this by causing a tingling sensation such as mild shock.
Why elbow tingling?
Most of the elbow cases are actually harmless. It’s just that in some other cases the ulnar nerve is under pressure, causing it to be easily pinched. This condition is known as cubital tunnel syndrome.
Hobbies lean elbows on hard surfaces, bend elbows for a long time, carry out heavy activities that are too pressing the ulnar nerve, or indeed there are problems with bone structure at the elbow, risking causing cubital tunnel syndrome.
