I figured some of you on this forum are quite experienced with all sorts of trauma related to the brain so I thought you could help out on this little OCD obsessive anxiety thought that seems to be bothering me a lot at the moment. Now this might sound stupid, but is our brains so fragile, that simply rotating our head (without shaking) to either the left or right rapidly enough with a sudden stop using your neck muscles pose a sufficient enough risk to be deemed as a potential cause of concussion?

I mean I originally did it to test if I got dizzy by turning my head fast, stupid I know, and I think I accidentally went too rough on the rotation and stopped my head too suddenly. I got dizzy and my neck hurt a little now but nothing serious, and I suspect the dizziness might come from my obsessive worrying of concussions and maybe due to the inner middle ear getting shaken around or something?

This just really bothers me, can the brain really crash into the skull by a simple movement from the body a.ka. the neck? I heard that rotational concussions are the worst

Thanks in advance!
