Post-concussion symptoms include:
- Loss of concentration and memory
- Noise and light sensitivity
Headaches that occur after a concussion can vary and may feel like tension-type headaches or migraines. Most, however, are tension-type headaches, which may be associated with a neck injury that happened at the same time as the head injury.
In some cases, people experience behavior or emotional changes after a mild traumatic brain injury. Family members may notice that the person has become more irritable, suspicious, argumentative or stubborn.
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.
