I'm so sorry to hear about Luigi. Cookie is the same way. I've found that it's easiest to not pick her up right away. But, also squat or sit at her level so she stops jumping so much. Yes, she gets in our face then but at least she's not going to hurt herself. We usually sit on the floor with her for the first minute or so until she calms down.
I would bet Luigi probably just bruised himself but I would keep an eye on him. Try my advice...hopefully it will help.
