Does the pain come after the fight is over? When the adrenaline wears off?

confirmed

but there are certain times where I'm like why do I punch and kick people in the face for a living?

I can answer that one for you. It's because you're really really really good at it. You have the rare gift of being able to be a professional athlete. Millions of guys with mundane, life-sapping jobs would kill to switch places with you I'm sure.
