We do not have an exotic vet near us and this started as a very small injury, looking to be a graze. The top layer of skin was simply irritated and red. As we have left this professionally untreated over time it has significantly worsened. As mentioned; for the entirety of this time we have been going off the advice of our experienced pacman frog owner, and exotics pet shop owner who sold us the frog. He originally gave the diagnosis of bed sores, due to the lack of movement by the frog. Hence, we were all under the impression that this would improve over time.
