Minor Head Injury

Learn more about minor head injury and how it is treated.

Overview

A head injury is any trauma that leads to an injury of the scalp, skull or brain. Injuries can range from a minor bump on the head to serious brain injury.

To prevent head injuries, wear a helmet when you perform activities that may put you at risk of hitting your head. These activities include bicycling, ice skating, roller blading, skate boarding, skiing, snowboarding and riding electric scooters.

Symptoms

Symptoms of head injury

The following signs and symptoms may indicate that you have a head injury:

  • Headache
  • Dizziness
  • Difficulty concentrating
  • Tiredness or changes in sleep patterns

Managing at home

Managing at home

During the 24 hours following your head injury, you and/or a caregiver should watch for symptoms, such as increasing drowsiness and/or confusion. These symptoms can point to a more serious injury.  

The following strategies can help you manage a head injury at home:

  • Take acetaminophen for pain
  • Avoid aspirin, other pain/narcotic medication or sleeping medication unless advised otherwise
  • Reduce the use of electronics, such as cell phones, computers or television, as these can make your symptoms worse
  • Avoid alcohol and stimulants, such as coffee
  • Avoid operating heavy machinery or other dangerous equipment
  • Avoid playing contact sports (such as, football, hockey, rugby and lacrosse) until you are seen by your family physician
  • Wait for a physician to give you permission to return to any activity that may put you at risk for another head injury
