I've had my female ball for about a year now, and the other day when she was climbing on a vine in her cage i noticed some discoloration on her belly





i want to say its scale rot, but being that i have no idea what im talking about (and you guys are the experts), please please please let me know what this looks like and what the treatment options are (if any).
theres a vet with a herp specialist like a half hour from my place, but im a student and not only am i pretty broke, but i dont have that much time in the next week and a half (finals :-( )

thank you!
