Would he be able to tell where somebody was injured? Either exactly or at least a general 'that person must be bleeding somewhere on their upper body'? Or would he just know that somebody had an injury? Also: would he be able to tell if somebody has more than one (minor) wound?

Has there perhaps ever been something in the comics about it (though I'm guessing there would be a certain amount of abilities as the plot demands going on...) Or has anybody any thoughts about it?
I'm thinking not of fresh injuries but the day after with everything already cleaned and stitched up if that makes a difference.
