Elena, your vet could be perfectly good with other animals, and maybe think he knows rabbits, but actually not doesn't. It's really hard when you're younger and you know things and you want certain things, but can't get them because those older than you say no. I agree that your vet is not the greatest, and I would suggest not using them in the future. Why? Because I used to have a vet that wasn't the greatest and I was too thick to know, and those vets cost the lives of5 of my rabbits. I wish, like you, I had known they weren't good, and had gone looking for a better one because those buns might still be alive (or at the least, I would think maybe 4 of them might have been). Thankfully I have now found a better one, and it makes the world of difference for your rabbit care. You're in a very hard position, but I do think it is worth looking around for another vet.
To me, she still sounds in pain if she is pulling her wound. How is her urine this morning? Is she still lying in wee? How is she in herself?
