Symptoms of Mild TBI and Concussion

Some mild TBI and concussion symptoms may appear right away, while others may not appear for hours or days after the injury. Symptoms generally improve over time, and most people with a mild TBI or concussion feel better within a couple of weeks.

Symptoms of mild TBI and concussion may affect how you feel, think, act or sleep

Symptoms of mild TBI and concussion are different for each person. Symptoms may change during recovery. For example, you may have headaches and feel sick to your stomach earlier on. A week or two after your injury you may notice you feel more emotional than usual or have trouble sleeping.
