This is not an emergency, you'll likely pay way more to be seen tomorrow because it's a holiday. I'd wait...this doesn't look serious to me at all, unless you see changes
as I described (bleeding, oozing, lots more redness), just keep her clean & resting & at the right temps. -and use a topical antiseptic as I explained earlier.
If you're in a larger metro area or very lucky, you might have emergency vet services available, but it's WAY more important that you see the most qualified reptile
specialist, rather than whoever is on duty for holidays & weekends. Regular vets don't usually train for reptile pets, & medical care is WAY different...many things are
toxic for snakes that are good for cats & dogs...you can waste money or even do more harm than good by seeing the "wrong" vet, even if they mean well.
