I was recently released from the hospital with a broken back and broken ribs due to a car accident. I was driving, heard/felt a popping sound in my left jaw and then a shooting, unbearable pain through what I m assuming is my trigeminal nerve. I felt nauseous and knew I was going to black out, apparently pulled over then crossed 4 lanes and did a 360 on the median guard rail. I woke up about 5-10 minutes later because 3 police cars, the fire engine and an ambulance were already there. This same sensation occurred to be 5 years before. I heard/felt a pop in my left jaw, an unbearable shock like pain to a nerve (after the pop, not during), felt nauseous, and blacked out on my driveway,splitting my head open and requiring stitches. I ve been tested for TN, inconclusive, do have some TMJ in the left jaw but not severe, and no one can tell me how to prevent this from happening again. I m just afraid of it happening while driving and me killing someone the next time.
