Symptoms

Persistent post-concussive symptoms include:

• Headaches
• Dizziness
• Fatigue
• Irritability
• Anxiety
• Insomnia
• Loss of concentration and memory
• Ringing in the ears
• Blurry vision
• Noise and light sensitivity
• Rarely, decreases in taste and smell

Post-concussion headaches can vary and may feel like tension-type headaches or migraines. Most often, they are tension-type headaches. These may be associated with a neck injury that happened at the same time as the head injury.

When to see a doctor

See a doctor if you experience a head injury severe enough to cause confusion or amnesia — even if you never lost consciousness.

If a concussion occurs while you're playing a sport, don't go back in the game. Seek medical attention so that you don't risk worsening your injury.
