Well, that takes a load off of my mind.

But, shaking your head violently repeatedly could cause an injury as the brain struggles to regulate fluid/blood pressure, etc.

Ok, this raises more questions. How hard do these jerks need to be to be considered 'violent,' as you say?
Also, these tics can occur up to 5 times in succession with an interval between them of about 2 or 3 seconds. Would this be considered to be shaking my repeatedly?
Additionally, how long does it take for the brain to regulate fluid/blood pressure once the levels have been disrupted by a head shake/jerk? In my case, does my brain have enough time to regulate fluid/blood pressure before the next jerk?
Thank you.
