What type of skin issue is this?

[Djbgolf]

There are only three 1/4” size lesions that a dry to the touch. I created a very moist shed box with peat and wondering if its too wet?

Those look like scarred wounds

I did have a heat pad on that may have burned him when he dug to the bottom.
Thx

I don't think it's an issue of too wet, those look like burns to me. If they are healed, they should subside some with many sheds. I would avoid with any pet, reptile amphibian invertebrate etc, putting heat at the bottom of the enclosure. In nature creatures dig down to cool off and it tends to confuse them if there is heat from below, this is often how burns and even deaths occur in burrowing pets

Makes total sense. Thank you!
