Well the way I view it is vets are good, but you should know your bunny better than the vet does. Maybe not the insides or how to fix them, but when it comes to physical appearance and behavior, you should always know more than your vet does when it comes to your personal bunny. It’s like when I took Nova into the vet. I knew her mouth was bugging her because she would sit and scrunch her face. I knew which side it was on because sometimes, about once a week, her right eye would be just the slightest bit weepy. Obviously I couldn’t fix it myself, I had to have the vet file them back to normal, but I was able to tell her what I thought the problem was before any physical exam was done, narrowing down the amount of time Nova had to be poked and prodded.
Plus in Bun’s case, it is probably like a broken toe for us. There really isn’t anything you can do about it except maybe pain meds (though if he is still eating he isn’t in that much pain). I guess they might give you antibiotics, but I think that might be rather excessive over-use of antibiotics… Just my personal opinion of course.
And if you do notice any swelling, pus, pain, etc, to the vet ASAP!
