This may be way off base, but if he is not eating also, could there be a problem with his teeth? Dental problems can cause an odd amount of symptoms. Just a suggestion.
Actually not so offbase… While the vet had him sedated for x-ray she probed all of his teeth to make sure he didn't have a bad root that was irritating the nasal passages.
are you still using that? Benadryl can be a sedative.
The first vet we went to recommended Benadryl, but we took him off after 2 days because it was making him congested and he had difficulty breathing.
If you don't mind cooking for him try:

the muttloaf. i cut the recipe in 1/2
I don't mind at all, especially if it gets him to eat. I will definitely be trying this! Thank you.
We should hear back on the results tomorrow. I'm just praying that we find something, anything, even if its not curable. I'd rather know its time to let him go so he doesn't suffer anymore than continue test after test while he continues to suffer.
Tonight he did a face plant into the floor trying to eat. Just tipped right over. Last night he had a bad nose bleed in bed. Its heartbreaking.
