I'm not disagreeing with any previous posters, but just offering my view. As I get to know my vet better I am becoming more likely to bring a reptile in to see her even if I'm not sure it is ill -- actually, especially if I'm not sure. I trust my vet's judgment, though, and I do substantial research on my end (not just when a snake is showing symptoms, but in general).
I agree that using antibiotics 'just in case' is in general a bad idea. It also seems that some vets really underestimate the possibility of a viral component to RIs, too, so getting clear on the causal factors is really important. Treating without testing wastes money, time and risks the animal's health.
But sometimes a qualified herp vet is pretty certain that the symptoms are indicative of an RI. If things are serious enough then getting meds on board may be more prudent than waiting for cultures and viral swabs to come back. I don't suspect that's what's going on in your case, just to clarify.
I do agree than panicking isn't warranted. Usually nothing is wrong. Having a vet's confirmation of that fact can be very useful, at least in my experience.
I suspect that going into the vet with an attitude that expresses a conservative outlook ('I'm pretty sure nothing is wrong, but would like to make sure') leads to more reasonable treatment recommendations than one that implies that you'll be upset if the vet doesn't move the earth and moon ('My snake's going to die oh no oh no!'). Little cues can move someone who's on the fence about a decision, and if a snake owner gives every indication that they're calm and reasonable then I think a reasonable treatment suggestion will follow.![]()
