Hard to guess what is really going on. I don't have any real advice other than to try and hold her to help her feel secure. You could also try just a little honey mixed in some warm water, just in case it has to do with a low sugar level. It couldn't hurt her and might help. Good luck and keep a close eye on her. If it gets too wierd or goes on much longer, a call to the vet just to reassure yourself might be a good idea.
