I tried making a video before we left for the vet, but he just stood there and I got impatient and picked him up and left with him.
While on the examining table, I discovered he had a large amount of yellow gunk in one ear. I showed it to the vet and she removed a large quantity of dried material and wax. She took it to the microscope and concluded it was both bacteria and yeast. So we are waiting for some ear drops to come in. They didn't have any in stock.
He still weighs 7.2 pounds, so he hasn't really lost weight after all.
She wouldn't prescribe a corticosteroid. She said it wasn't good for rabbits, and I didn't want to challenge her on her opinion.
She instead prescribed a narcotic, bunorphine, or something like that. She says I have to put it in his mouth, but he isn't to take it with food and swallow it. I can give it to him once or twice a day. I forget to ask how long it would take, to take effect. I'm thinking a narcotic would take effect fairly rapidly. So that means I should have him out within half an hour of giving it to him.
Now here is a really crazy question. Has anyone tried marijauna for a rabbit in pain? I've heard that some people use it for chronic pain, arthritis, and seizures. Maybe he could eat a little bit? My wife has access to medical marijauna drops, 50:50 cannabidiol to TCH. Maybe a drop would help him?
Edit: Here is one article of many that I found on cbd for rabbits:
