The vet i use is very prestigious in the exotic animal world. Went to the vet the first time it happened, had a couple of lumps on it's face , they lanced on and it was a hard mass they couldn't identify. Clean terrarium and some topical baytril if I remember correctly and everything healed up and lumps disappeared. While I was cleaning the terrarium I did notice the frog had buried it's poop and was sitting up against it. A few months later, another lump pops up, and when I go to examine the frog, I was again find buried poop and it's right against where the lump was forming. Once again, cleaned the terrarium and it cleared up on it's own. The other frogs I have will all poop and move far away from it or climb in their water bowl to poop, it's just that one that will bury it right there where she is sitting.
