It is interesting how new words pop up. This one popped up the other day.
die Narbe - scar
We all have little scars from falling off bikes and skinning are knees as kids. We can also have much larger scars from serious accidents.
There are even scars that we can't see, emotional scars. Emotionale Narben. It more likely that one would say emotionale Wunde, auf Deutsch instead of emotionale Narbe. However it is still correct and can be used.
emotional - emotional
die Wunde - wound
