Most head injuries aren’t serious. You don’t usually need to go to hospital and should make a full recovery within 2 weeks.

Go to A&E after a head injury if you or your child have:

  • been knocked out but have now woken up
  • been vomiting since the injury
  • a headache that doesn’t go away with painkillers
  • a change in behaviour, like being more irritable
  • problems with memory
  • been drinking alcohol or taking drugs just before the injury
  • a blood clotting disorder (like haemophilia) or take blood-thinners (like warfarin)
  • had brain surgery in the past

You or your child could have concussion.

Symptoms usually start within 24 hours but sometimes may not appear for up to 3 weeks.

Find your nearest A&E

Call 999 if someone has hit their head and has:

  • been knocked out and hasn’t woken up
  • difficulty staying awake or keeping their eyes open
  • a fit (seizure)
  • problems with their vision
  • clear fluid coming from their ears or nose
  • bleeding from their ears or bruising behind their ears
  • numbness or weakness in part of their body
  • problems with walking, balance, understanding, speaking or writing
  • hit their head in a serious accident, such as a car crash

Also call 999 if you can’t get someone to A&E safely.

How to treat a minor head injury

If you don’t need to go to hospital, you can usually look after yourself or your child at home.
