Head trauma can be fatal. The effects from some types of head trauma may not appear right away. So it’s important to get medical attention for any head injury.
Do not move a person with a head injury unless it is necessary to save his or her life. Call 911 and wait for help. Head trauma often comes with severe neck injury. Sudden movements can result in paralysis.

Call 911 right away after a head blow that results in:
Daze, confusion, or loss of consciousness
Memory problems
Headache
Nausea or vomiting
Pupils dilated or different sizes
Severe bleeding
Blood or watery fluid leaking from nose or ears
Broken skull or a soft spot on skull
A neurological exam is likely. This is a series of simple questions and tests that evaluate the nervous system. Reflexes, response to pain, and mental state are assessed.
The doctor shines a bright light into the eyes to check how the pupils respond. This can reveal more about any head injuries.
A computed tomography (CT) scan may be done. This test combines x-rays and computer scans to create detailed images of the brain.
Severe head injuries often need immediate surgery. In certain cases the injured person will be watched closely and taken for surgery only if injuries become worse. After surgery, special care helps prevent further brain damage.
Minor head trauma may need little treatment. The doctor may suggest using cold packs to reduce swelling and pain.
Call 911 or return to the ER right away if the affected person:
Becomes very drowsy or confused.
Has a headache or trouble seeing.
Has a stiff neck or muscle weakness.
Vomits.
Has seizures.
