I would recommend getting a culture done if the infection came back. The stress could be a factor, I never handled my girl or fed her until she was feeling better when she had her infection, but I had to give her needles for her meds after the vet visit so handling was limited for only that (needles was stressful for both of us, haha). I was told a culture should have been taken first thing as well, the vet just gave me Baytril and needles and the dosage I was to inject her with and showed how to do it. It took about 3 weeks before her nose started clearing up and now she's perfect again.
I never tried this, but apparently this home treatment method has worked really well for some! http://ball-pythons.net/forums/showt...-from-Home-DIY
But I think this is for when you just start to notice the infection coming on, it sounds like your guy has had it for a while and will need the antibiotics.
It looks like you're on the right path now going back to get the culture and antibiotics re-evaluated!![]()
