I don't know what I would do since I'm not in your situation. Probably have them pay all out of pocket medical at least.
I would not be happy with the stitches or shot plus part of your eyebrow gone which probably won't grow back.
Hope your feeling better soon.
One of the ceiling fan blades broke off our fan in the dining room & it flew off & dented the wall. That was a good place for it to hit. If it had flew any place else it would have went through the kitchen or through the glass on the french doors or windows. It was very scary. Now we check the blades every once in a while.
