Brain injury: If you are feeling dizzy or nauseous you should seek medical attention right away. If there is any weakness in an arm or leg, visual changes or other neurologic changes you need immediate medical attention. However persistent headache could mean concussion and you see a doctor soon. Mild brain injury does have an effect on work and school. Kids are more susceptible than adults.

Very small one might not be noticed at all.In severe cases, you could lose consciousness. Also, if a hemorrhage grows, it could become more noticeable. Somethings can progress over minutes/hours, while others can take days.
