The hard mode gamer in me would like wound info to only be available with some sort of medical or biotech roll. But that's probably asking for too much. Ideally a character might know which part of their body is wounded, but not the extent of the wound.
As long as I'm asking for the impossible here, it would be great if it could be automatically coded. So that when characters look at themselves it does the wound assessment based on their skills and stats. In other words, they don't actually need to use a skill as a separate command.
You are either suffering from a GSW or a stab, cut, bruise, burn, bad relationship with your father, or nothing. Until the other stuff is ever made a thing, then KISS (keep it simple stupid) methodology should apply.
I do not think glance would be a great use for surfacing this information. Glance is less about looking at yourself and more about looking at others.
I can see this being added to your own 'look me' though, as you would definitely not need medical skill to know you got slashed in the thigh or shot in the foot.
