I hope a Vet has checked this as that ear drum can rupture and there could be permanent hearing loss not to mention the pain. :-(
Apply cold compresses (VERY GENTLY) to her ears for 10 minutes at a time, and off for at least ten minutes. The coldness will make her hears feel better for a short while (make sure you are NOT using something wet - put a few ice cubes in a baggie, and wrap this with a thin cloth). Tip: think of what would feel good to YOU if you had this problem. Answers come right away! - Blu PS: never use human medication on animals unless told to do so by your vet.
The Vet can't see her for a couple of days??? That is serious and the ear drum can rupture and it is very painful for the dog.
You call the Vet and put your foot down or call another Vet.
