What symptoms to expect

It is normal after a head injury to experience the following:

• Mild headache
• Sensitivity to bright lights
• Feeling sick (without vomiting)
• Mood changes - feeling angry, anxious, irritable, or struggling to rest are common symptoms
• Difficulty concentrating and retaining information.
• Feeling tired or needing to sleep more

Your recovery

These symptoms should resolve over the next two weeks. If they persist or you have concerns please visit your GP.

You can take simple over the counter analgesics (painkillers) such as paracetamol to help.

• Do rest.
• Do keep well hydrated and avoid stress where possible.
• Resting includes avoiding strenuous activity or rough sports.
• Avoid reading small text or screens such as computers, phones or TV as concentrating on these can make your symptoms worse.
• Do not have alcohol or any sedatives (medicines that help sleep) following your head injury for at least 48 hours.
• Do not drive until you are fully recovered. 
• Do not return to work, college or school until your symptoms have improved. 
• Do not participate in contact sports for at least 3 weeks.
