My beardie's skin has gone grey and discoloured all down her tail and a patch on her back. This has happened before, but it was only a tiny bit by her mouth and it disappeared within a few days. Have taken her to the vet previously for this reason but they said she was healthy. It seems to disappear but then come back a few months later. I have read that it's due to shedding, however she only ever seems to shed a tiny bit around her eye. Should I be worried? (Have tried to upload a photo but doesn't seem to be working, not sure why)
