24 hours post-op and with all she went through, I wouldn't be terribly concerned about her not wanting to eat. She HAS to drink.
How much pain are we talking? Is she crying? Shaking? Just a bit slow? It can sometimes be hard to completely stop the pain after abdominal surgery, but when it is still to a certain point a day later (crying, etc.), then other drugs can be tried. Your girl needs to see a licensed veterinarian right now, particularly for that amount of bruising.
