Yesterday evening, I had a really strange experience. I walked pretty fast through an open door, because my food was ready. I wasn't catious enough due to beein in a hurry and snaged with my left under arm on the left door frame. This resulted in a very fast turn of about 90 degrees of my whole body. The head itself did not move the full 90 degrees, because of the necks rotational ability(I hope you know what I mean here).

In conclusion, this incident resulted in extreme fatigueness a few minutes after it happened. I was so tired that I fell asleep. Today I'm still a bit dizzy. Actually, I have no explanation of this. I also don't know wether this can be called a subconcussive impact, as the head itself didn't hit anywhere.

Chris,

First, subconcussive impacts have a cumulative effect when one suffers hundreds of them over a few months. One infrequent impact is not a big deal.

Did you fall sleep before or after your meal ? If after, it could be because you meal caused an increase in blood sugar. This can cause drowsiness and sleep.

A short bout of anxiety from the "Did I hurt myself bumping into the wall?" thought can also cause sleepiness.

I fell asleep after meal, but nonetheless I'm pretty sure it had to do something with the impact. I also get this feeling when I bump my head slightly. Not sure where it is coming from but look at this search result, it seems that I am not the only one who feels this

and I also know what the discussion about subconcussive impacts is about(especially football). But what does in fact count as a subconcussive impact? I did't hit my head, the impact was just on the arm. Because of my extreme head sensitivity, I also feel it in my brain, when I lay on a pillow and hit the pillow with my hand(that occasionally happens during sleep). Can this be called a subconcussive impact?

Typically when I have seen articles on sub-concussive impacts affecting the brain, it has been referring to many of them during a season. Such as heading many soccer balls, or being in many football tackles.

I don't think hitting your hand against the pillow while your head is on the pillow would come even close to the forces required for it to be considered a sub-concussive impact. But that is just my understanding of it.

I suffered and continue to suffer from anxiety, which often resulting in questions like you are asking now. You would be very surprised at the array of symptoms that just anxiety can cause.

Yahoo answers is a lousy place to get concussion info. Please ignore it.

This pillow event is neither a concussion nor a sub-concussive impact. You reaction is likely just anxiety.
