I don't recall anything of that sort making me vomit.

Or hmm. I think I was in primary school when a cousin fell and had a little accident. There was only a little cut on his forehead but it needed stitches. I was really scared and started throwing up later.

Nowadays though, I don't think something like that would make me vomit... but I don't actualy look for long enough to decide if it would happen or not.
