Corn Snake tail rotting?

[JakeDaSnake]

Hi, my corn snake is about 20 years old. She has always been healthy and I just noticed this thing with her tail about a week or so ago. She seems normal and moves about her aquarium as usual.

I took her to a serpentarium a few days ago and they confirmed that new scales are forming and she looks otherwise healthy.

I have called veterinarians and its going to be late next week or the following before I can schedule an appointment and also get time off from where I work to take her.

I am not able to determine if perhaps a mouse chewed on her to cause this. I was 7 when I purchased and named this snakelet and the serpentarium where I purchased her (long out of business) sold us pinkies and later as she got bigger, live adult mice. Years later, I tried to get her to eat thawed frozen mice but she basically ignored them and they rotted. Any help/advice will be greatly appreciated.

It's necrotic. It needs vet attention to ensure it isn't traveling up the snakes body and amputation may be needed.

There could be underlying health issues going on internally.

The serpentarium may have good intentions however, they cannot run any internal tests to see if there's infection or other things.
