ELI5: when we sleep awkwardly why does it hurt so much when we try to turn our neck one way or raise our arms above a certain height?

Let’s say you bend your finger back a bit. It hurts, but only a little bit. Still, it’s enough for you to move it into a more comfortable position.

Let’s say you bend your finger back a bit and you are asleep. It doesn’t hurt enough to wake you up. Your finger is in an awkward, slightly painful position for 8 hours. In the morning, it hurts a lot.
