What is head cracked open?

Head cracking open can occur due to severe head trauma caused by accidents, falls, or violent blow. The skull is the protective layer of the brain and any damage to it can cause severe injuries like skull fracture, brain injury, and even death.

Symptoms of a head cracked open may include bleeding from the ear, nose, or mouth, irregular breathing, loss of consciousness, seizures, vomiting, confusion, and severe headache. In case of such an injury, it is important to seek immediate medical attention. The patient may need emergency surgery to repair the skull and stop the bleeding. Following proper medical treatment, the patient may need to undergo rehabilitation to recover from any motor and cognitive disabilities resulting from the injury.
