Tip - Did screaming, yelling and going berserk somehow relax the muscles pain receptors

It was a miracle! An anticipated 3 days of agony had been blasted away in a fireball of emotion.

Did screaming and yelling and going berserk somehow relax the muscles, or release endorphins, or somehow make the pain receptors stop recepting? At any rate, all was well with the world. Thank goodness. I had 3 days to go to showtime, and there was a lot of work to do.
