What happens when you hit your head on a hard surface?

How Does Your Brain Get Hurt? A hard blow to the head can shake your brain inside the skull. The result: bruises, broken blood vessels, or nerve damage to the brain. A hard hit that doesn’t cause bleeding or an opening in your skull could be a closed brain injury.

How do I know if my head injury is serious?

Seek immediate emergency medical care if you have danger signs

How long does a head bump last?

Most head trauma only causes a scalp injury. The deep headache usually clears in 24 hours. The scalp pain at the site of impact may last 3 days. The swelling may take a week to go away.

How long does it take for a head bump to go down?

A hematoma is not a bruise. It is a pooling of blood outside of the blood vessels deeper in the skin than a bruise occurs. Trauma is the most common cause of a hematoma. Depending on the cause, it can take anywhere from 1 to 4 weeks for a hematoma to go away.

What happens when you get a bump on your head?

The forehead and scalp have an abundant blood supply, and injury to these areas often results in bleeding under the skin. When the bleeding is in just one area, it causes bruising and swelling (hematoma). Keep in mind that even a minor head bump can cause a large swelling.

What happens to your brain when you hit your head hard?

A concussion is a mild traumatic brain injury that causes temporary brain dysfunction (i.e., concussion symptoms—more on that later) that almost always goes away with time. A blow or jolt to the head causes rapid movement of the brain inside the skull, leading to changes in how the brain works.

What happens if you get a whack to the head?

Very rarely, a serious whack to the head can result in a skull fracture causing potentially deadly bleeding (hemorrhage) and/or a blood clot (epidural or subdural hematoma). You’ll pretty much always get knocked out from a concussion first.

Can a closed head injury cause brain bleeding?

A closed head injury is one where something hit you very hard on your head but the object did not break your skull. An open head injury occurs when the object breaks your skull and enters your brain. Both types of head injuries can cause bleeding.
