Mark or Bud if you're out there, please help me out with this. (Or anyone, please.) I don't want to worry my entire long weekend.

My cat was sitting in an open window and I went to lean down to give her a kiss on the head and bumped my forehead/a little above my forehead on the hard plastic sill that sticks out at the top where the window is open. (The part you pull down to close it or up to open it)

Since then, I've felt out of it, dizzy, headaches, blurry vision, etc. I keep trying to tell myself that a bump like this wouldn't bother someone without the history.

Do you think this qualifies as a concussive impact? (Banging my forehead on a plastic window sill?) How many G's would this even be?

Thank you, appreciate it.
