Ouch I would get that baby some medical care like yesterday, it looks like burns are you using a in tank heat rock? Another thing might be is under the glass heat pad that is not on a thermostat, I ask because my male goes in his cave and moves all his aspen to the sides in the cave and lays on the glass I put more aspen in and he moves it' and if that pad was not on a thermostat it got to hot to the touch on my hand, I'm no expert but this gives you some things to check. I hope he heals and is OK.
