OH WOW I WOULD BE CHANGING VETS, I KNOW SHE HAD TO BE HURTING . SO SORRY . HOPE SHE DID OK.
I am surprised that her vet did not give her post surgical analgesics. I would call your vet early tomorrow to request 4 days of Rimadyl.
In the meantime the only thing you can really give her is 1/2 of a 81mg baby aspirin every 6 hours.
