You were rushing to get home to start dinner, and another vehicle rolled into your car as you were leaving the parking lot. A small jolt occurred during the accident, but no one was injured. You apologize, shrug off the minor mishap and go your separates ways.
The next day, you notice some trouble breathing. Its allergy season and you wonder if an allergy shot might help. Several days later, you develop a mild headache. You notice your balance is a bit off. The headaches turn into migraines. Your eyesight blurs so badly that you cannot read or watch television. Your daughter insists on driving you to the hospital.
