Hello
Thank you for the information and sharing your story. I would say that based on the information provided I would call your vet and ask for help. It migh t be pain, infection or secondary disease process. An appetite stimulant might also help. Regardless there is a cause for her nausea and inappetance and that needs to be diagnosed and treated. Start there.
I wish you luck.
Keep us posted
