Help!!! Ball pythons body is attacking itself

[GoingPostal]

Slipped skin is associated with vitamin C deficiency due to malnutrition. If that were the case the snake would be severely underweight and the vet would have noticed.

I hate to say it but you did dilute the chlorhexidine right? Also, do you live with anyone who could have applied a caustic substance to the snake?

Mountainside-medical.com will sell silvadene without a prescription. I would order some.

Wasn't there a severely underweight snake on here recently that had seen a vet and it wasn't brought up? I never assume a random vet will be snake experienced and having not seen the snake it could be in poor shape or fed improperly. The "goo" and large chunks of scales falling off sound similar though. A picture might help get a better idea for sure.
