Welcome to BB. I’m sorry to hear you need to post about such a worrying situation.
Since it’s been two days, I highly recommend seeing a rabbit vet for a professional opinion.
On BB’s end, getting exact details on what you feed your rabbit could help members pinpoint the potential cause of the distress.
1) What do you give her to eat?
2) How much does she receive?
3) How long has she been receiving each individual food (i.e. how long on this hay, pellet, veggie, etc…)?
4) How long have you had her?
The priority is that she eats. Make sure she eats and is passing poops. If she does not for 12hrs or more, take her to an emergency vet immediately.
To try and alleviate her discomfort, purchasing some simethicone (infant gas drops) at the store and giving her some to take may help. It’s for dealing with minor gas, but this seems to be a pretty big episode. However, it’s worth a try until you can get her to the vet. She may need motility drugs.
