Currenly the Check Injuries action is pretty vague to the point of being pointless, and could do with providing better information.When used, it will typically say major/minor injury, and mention bleeding, but usually thats 'the bleeding obvious' (excuse the pun). Currently it's just not worth doing, since that information is not telling us anything we don't already know.

What would be better is if it could state exactly where the injury is and what type.

For instance;
Major injuries, heavy bleeding right leg and chest.
Unconcious. Heavy blood loss.
Torniquet applied to left leg.

This would help, as it currenly is not visibly obvious in game where the actual injuries are, due to animation limitations (in real life heavy bleeding is typically more obvious where it is occuring)
