I was just pointing out that the heat rock should not have even been mentioned. Not for a snake. Ever. Period. So great that their isn't one. Since its not a burn I can only imagine it's scale rot which is typically caused by poor husbandry and unsanitary conditions. I still stand by the notion that the animal should probably see a vet for the bubble if nothing else, but if the scale rot had gotten bad enough to look like a burn it should really still see a vet.
