Poorly bunny

Holly spent the afternoon at the vets. This morning she wasn't eating, looked uncomfortable and then we found her with both of her front paws in her water bowl.
She was given a pain injection and was force fed by syringe and didn't go to the toilet all the time she was there.
When she got home, she went to the loo and ate all the fresh and dried food put in front of her as if nothing had happened? Pleased she is well again though!
