Looking at your other thread, I'm more and more convinced that dehydration is part, if not most, of your problem. If you are using that stick on dial to measure temps, and that is reading 90F, your tank is probably too hot, especially given that you have two lamps and a UTH running. The dial is a few inches above the substrate, not on the substrate where the snake actually is. So, I would recommend getting either a thermometer with a probe or a temp gun ASAP. I would also suggest a soak in lukewarm (80-85F) water. I'd put water in a shoebox tub so that it comes about halfway up the snake's side (you don't want him to have to swim). Put him in the shoebox, and leave him for about 15-20min.
