For example, if a rock hits your nail bed. It eventually grows out with the rest of the nail, and isn’t painful.

it’s damage. Fracture a pane of glass in the right way and it, too, will turn milky white. It’s the effect of a bunch of tiny fracture lines all refracting light in random directions, resulting in a while color.

You nail is strong and made up of dead material, so that doesn’t really hurt you, What it does mean is that it did it’s job and protected your toe from a pretty hard blow, which is exactly what it is meant to do.
