What to do
- After a blow to the head – no sport and no work, rest.
- Serious injury – ask them not to move the head and neck; if they are lying down, support the head with your hands.
- Call 112 if they lost consciousness even briefly, vomit more than once, behave oddly or speak unclearly, have a seizure, a limb is numb or weak, balance is affected, they see double or blurred or light hurts, blood or clear fluid comes from the nose, ears or mouth, or a severe headache does not pass in 2 hours even after painkillers.
- Only a bump, a mild headache or nausea – rest and watch.
- Even if everything seems fine, watch for 24 hours: signs can appear later.
- A suspected concussion must be assessed by a doctor.
