Just because you got punched doesn’t mean that the damage (a very obvious and unappealing one at that) in your face is “facial nerve damage”.
Firstly, a simple punch can only give you pain and a bit of facial paralysis for days or weeks. And secondly, a punch can only affect the external of your face and not that sensitive nerve located in your skull, like in the case of facial nerve damage. After getting punched, your face is still considerably normal except that some parts of it have black aching patches and you can still laugh about your rather, laughable condition.
