Head injury and concussion
Most head injuries are not serious, but you should get medical help if you or your child have any symptoms after a head injury. You might have concussion (temporary brain injury) that can last a few weeks.
Go to A&E if:
You or your child have had a head injury and have:
- been knocked out but have now woken up
- vomited (been sick) since the injury
- a headache that does not go away with painkillers
- a change in behaviour, like being more irritable or losing interest in things around you (especially in children under 5)
- been crying more than usual (especially in babies and young children)
- problems with memory
- been drinking alcohol or taking drugs just before the injury
- a blood clotting disorder (like haemophilia) or you take medicine to thin your blood
- 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.
You should also go to A&E if you think someone has been injured intentionally.
Call 999 if:
Someone has hit their head and has:
- been knocked out and has not woken up
- difficulty staying awake or keeping their eyes open
- a fit (seizure)
- fallen from a height more than 1 metre or 5 stairs
- problems with their vision or hearing
- a black eye without direct injury to the eye
- 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 at speed, such as in a car crash, being hit by a car or bike or a diving accident
- a head wound with something inside it or a dent to the head
Also call 999 if you cannot get someone to A&E safely.

How to care for a minor head injury
If you have been sent home from hospital with a minor head injury, or you do not need to go to hospital, you can usually look after yourself or your child at home.
You might have symptoms of concussion, such as a slight headache or feeling sick or dazed, for up to 2 weeks.
hold an ice pack (or a bag of frozen peas in a tea towel) to the area regularly for short periods in the first few days to bring down any swelling
rest and avoid stress – you or your child do not need to stay awake if you're tired
take painkillers such as paracetamol for headaches
make sure an adult stays with you or your child for at least the first 24 hours
do not go back to work or school until you're feeling better
do not drive until you feel you have fully recovered
do not play contact sports for at least 3 weeks – children should avoid rough play for a few days
do not take drugs or drink alcohol until you're feeling better
do not take sleeping pills while you're recovering unless a doctor advises you to
See a GP if:
- your or your child's symptoms last more than 2 weeks
- you're not sure if it's safe for you to drive or return to work, school or sports
