My drivers side headrest busted open and hit me hard in the back of the head. I was driving around 45 mph when I heard a loud pop and I got hit in the back of the head. This caused me to panic and swerve, thinking I got hit by another driver. My mother, child, and myself were in the car at this time and it was a safety hazard, not only to me, but them as well. Being hit by by the head rest set off a bad migraine and neck pain. I have not had it looked at as I can not afford to do so.
