Whenever I think about physical injury, broken bones, surgery, stitches, wheelchairs, etc. I get this strange shivery feeling in my sides and inner arms. It's not the same as the back-shivers you get when you're scared of the ghosts or the dark or whatever. Also actual gore webms or whatever don't usually trigger it. It's purely based on the thought of me, or people and animals I know, getting hurt or disfigured. Is there a name for this, the emotion or the feeling? Pic related is where I feel it.
