Head injury, minor

Minor head injuries are common in people of all ages and should not result in any permanent damage.

The symptoms of a minor head injury are usually mild and short lived. Symptoms may include:

  • a mild headache
  • nausea (feeling sick)
  • mild dizziness
  • mild blurred vision

If you or your child experience these mild symptoms after a knock, bump or blow to the head, you won't usually require any specific treatment. However, you should go to your local minor injuries unit or accident and emergency (A&E) department for a check-up.

If your symptoms significantly worsen or you develop any new symptoms after being discharged, you should return to A&E straight away or call 999 and ask for an ambulance.

How common are head injuries?

Each year in England and Wales, around 700,000 people attend A&E departments with a head injury. Of these, over 80% only have a minor injury.

The most common causes of head injuries are falls, assaults and road traffic collisions.

Children are more likely to sustain a minor head injury because they have high energy levels and little sense of danger.

Treating a minor head injury

You can usually recover from a minor head injuries at home. Most people will make a full recovery in a few days.

For the first 24 hours after the injury, it's important for someone to stay with the person who was injured, to keep an eye out for any new symptoms that develop.

It is also important to rest and avoid aggravating the injury with stressful situations and avoid contact sports until fully recovered.

Mild headaches can be treated with paracetamol, but always read the manufacturer’s instructions and remember that children under 16 should never be given aspirin.
