I have a question..I was just out riding my car and the car just stopped all of a sudden while I was going mabe 35 km/h and there was a quick stop and I was a little shaken by it. I am afraid I have once AGAIN concussed my brain..I feel a little nauseaus and just feel like I can't handle one more concussion..Would this incident be called a concussion or a decompensation? Should I go to the doctor?
