What happens after a head injury?

It's normal to have a headache and nausea, and feel dizzy right after a head injury. Other symptoms include ringing in the ears, neck pain, and feeling anxious, upset, irritable, depressed or tired.

The person who has had a head injury may also have problems concentrating, remembering things, putting thoughts together or doing more than one thing at a time.

These symptoms usually go away in a few weeks, but may go on for more than a year if the injury was severe.

Get help if you notice the following symptoms:

  • Any symptom that is getting worse, such as headaches, nausea or sleepiness
  • Nausea that doesn't go away
  • Changes in behavior, such as irritability or confusion
  • Dilated pupils (pupils that are bigger than normal) or pupils of different sizes
  • Trouble walking or speaking
  • Drainage of bloody or clear fluids from ears or nose
  • Vomiting
  • Seizures
  • Weakness or numbness in the arms or legs
