I don't have sound right now, but it looked like she had something stuck in her throat (or felt like she did). Did the vet give you any good reason for wanting to do all the same tests over? If not, then I would have to say try yet another vet, and talk to them on the phone first to make sure they're willing to work with the information you've already got. It would be great if all vets were truly caring and knew what they were doing, unfortunately it's not always the case. Good luck!
