Hi. I had a concussion six months ago, but my symptoms, mostly headaches, have subsided. However, today I was driving and was forced to slam on the breaks which caused my head to jerk forward somewhat. It was from about 35 mph to stopped in what felt like less than a second (but I'm not sure). Being extremely concerned about another TBI, I immediately began panicking. My head jerking forward is what was so scary, as I can picture my brain hitting the front of my skull. I have had a headache behind my eyes ever since, and I have felt somewhat groggy. I am not sure how much anxiety is playing into this, but I cannot shake the thought that I caused more irreparable damage. Thanks for any insight on how I should be handling this.
