I still stand by my first answer, not a burn scale rot due to the previous substrate used which created a damp unsanitary environment.
It is minor it will go aways on it's own in a shed or two.
Stop using the cream if it is oil based it will lead to even more issues and find another vet for next time.
Is there a specific way for me to tell if the cream is oil based or not? And are you sure it's a scale rot? :/ im just confused seeing as I've gotten way too many answers by people with different opinions..
