My retic has a swollen mouth...

[zina10]

The thing is, most of the pus forms a semi solid mass. There may be some liquid around it, but whatever drains out of there (esp. on its own) is by far not all that is in there.

Putting F10 fog in there is not getting the meds where it needs to go. First of all, isn't the concentration of the F10 that is sold in the US the wrong one for fogging??

If anything, that should help respiratory issues by getting the sanitizer near the lung tissue.

So, the vet thought it may be a tumor, but now thinks respiratory ?? But it behaves and looks like an abscess? And he did no diagnostics, its all guess work ? No treatment other then send you home to do fogging?

An abscess has to be cleaned out completely and thoroughly. Which in a reptile means excising (draining liquid, scooping solids, flushing thoroughly). After which there should be antibiotic injections, so the meds go where needed. An abscess harbors nasty bacteria.

The fogging is not going to get all the infected necrotic tissue out.

If anything, if you are extremely lucky, the snake will simply survive on her own. Not due to F10. If you are unlucky, that bacteria will keep growing and the infection will turn her septic.

I would find a vet that is willing to actually DO something, instead of risking that snakes life by DIYing her...

But that's just what I would do
