Hi calmwaters,

I can tell you that since my last tbi, I have struggled with a ton of anxiety over this question. Just the other day I stalled out a manual transmission car causing my head to jerk forward and then whip back very abruptly. I wasn't going very fast, but I felt so strangely afterwards that I was sure it had been enough force to do me in.

This was not the case. My neck has been a little sore, but I did not have any new tbi/pcs symptoms following the head jerking. I think that my head does not like too much movement at all, including head jerking, shaking, spinning etc. So I do try to avoid lots of motion because it does make me feel dizzy immediately after, but so far has had no lasting effect.

My guess is that you'd have to jerk your head with a lot of force to cause a full blown concussion, probably hard enough to damage your neck as well, but I'm not too sure. Is there something you experienced recently that you are worried about?
