Emergency? Need advise

I posted this in the care section but it was suggested I post a link here because this thread gets more views. I'm sorry to break the rules but I'm very nervous.

i'm really sorry to hear about your rabbit what everyone has suggested in your other posts i agree with, have you no pancur in the house to give him? keep him warm too. it really could be anything i hope the vet can tell your clear. keep tempting him with food lots of tasty treats to temp him. fresh parsely and herbs etc.
