So sorry, it is stressful on you but you're doing an awesome job, I certainly can't do better or offer any better advice.
Just about anything can stress out my current sneezers from skipping a salad to dealing with a pig of a pen mate to treating somebunny else in the room with meds to having dirty litter to going away for a night to turning on a ceiling fan, and those are just the few things I noticed, lord knows what I haven't noticed.
I think bugs just run their course as well. Or at least I hope so.
A number of bunnies here had been sneezing for the last month or more, a full course of Baytril didn't do much and I ran out of Chlor Palm a few days short of the prescribed period and couldn't get more before it was too late. They had seemed pretty close to symptom-free but maybe not for the full 72-hours (it's recommended that antibiotics are continuted for at least 72 hours after symptoms disappear), and I was having trouble telling whether Mickey was wheezing or snoring (he normally doesn't sleep with me) so I finally got back to the Vet on Monday to make sure his chest was clear and I got $150 worth of more antibiotics. I haven't heard one sneeze or wheeze from anybunny since I got back so I'm holding off.
I think observation is the best tool and the most stress-free, although it's tough to know what they're thinking and the body is reacting to.
It also sounds like there isn't much in the way of stress-free treatment options other than the holistic approach you're currently on.
Hope Loki hangs in there for years to come.
