Squished hand: the bandage is likely a little snug on purpose as some compression keeps swelling down. (Along with you keeping your hand above the level of your heart.) Just make sure your fingers don't turn white... or blue. (If they go green, then there's always the 'hook' option)

The pain should begin to abate rather quickly. (That's 'quickly' to the rest of us. Not so much, to you.)
