Most head injuries are not serious. You do not usually need to go to hospital and should make a full recovery within 2 weeks.
You or your child could have concussion.
Symptoms usually start within 24 hours, but sometimes may not appear for up to 3 weeks.
Also call 999 if you cannot get someone to A&E safely.
If you do not need to go to hospital, you can usually look after yourself or your child at home.
It's normal to have symptoms such as a slight headache, or feeling sick or dazed, for up to 2 weeks.
To help recovery:
hold an ice pack (or a bag of frozen peas in a tea towel) to the injury 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 paracetamol or ibuprofen to relieve pain or a headache – do not use aspirin as it could cause the injury to bleed
make sure an adult stays with you or your child for at least the first 24 hours – call 111 for advice if there's nobody who can stay with you
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
