Hmmm that was a really weird noise. I thought is sounded like it was coming form the larynx (voice box) rather than the nose and wondered about a particle being lodged there and irritating the vocal cords or even a laryngitis (a particle being morel likely).
But she did not seem to be breathing rapidly (as she would if actually choking) and seemed quite bright and alert in her self.
If it is just fear (and I would doubt that) then nothing beats frequent, gentle contact and handling. Get a wire foldable play pen and sit in there with her and let her investigate you at her own pace.
We have had some timid syrians and they all come around eventually, some just take longer than others.
