Hi all, i am 4 months into PCS. I have a concern that I want to address to. Whenever I drive my car, I have had several instances when I have to suddenly apply the breaks and there is a sudden jerk to my body in the forward direction but there is no impact to the head whatsoever. All these instances have taken place at a speed of less than 5 mph as I drive very cautiously and slow these days. Will this in any way cause any harm or further impact to my brain ? Sorry maybe the question is vague or funny, I was concerned about it so asking..thanks
