Hi ever since I’ve had my 3rd concussion I’ve been extremely worrisome and just down right anxious from every bump or anything and need reassurance from a doctor or even a person if it’s as simple as a small bump that it’s not a concussion. So I was in a car that accelerated quickly to 50 km/h for 2 seconds and then suddenly braked and I’ve been feeling all the symptoms of a concussion. Am I just being crazy or is it actually possible at that speed
