Well, Wiki is home now. She’s groggy and clumsy, coming off her anesthesia, but doing well. Short story is they found nothing. $750 later, she’s had a complete upper respiratory and nasal workup, x-rays, cultures, etc. She apparently had a “massive” amount of mucous, much to the surprise of the attending. No polyps, no other nasties to see. Best bet at this point is that FHV-1 as a kitten destroyed most of her mucosal tissue, leaving her particularly prone to allergic rhinitis, which she will live with indefinitely.
Provided the cultures don’t come back with anything interesting, it’s back to antibiotics, antihistamines, and steroids as needed.
