I'm sorry I haven't been online for this, haven't read the full thread.
Can you give him Baby Motrin. I give my small rabbits about a quarter of a tablet. Just make sure he drinks a lot of water with it.
Otherwise keep him quiet. The vet would give a diagnosis and possibly suggest surgery, but they may also just give him a shot of pain meds and maybe steroids.
I think another bunny, Coco, just got better through rest and anti-inflamatories. Worth a shot.
And I think the members here have made stated their opinions on care, now I hope we all support and respect our fellow member with her decision.
