I won't allow my snake to be uncomfortable, sorry. He eats every 5 days, sheds perfect, and is healthy otherwise. Maybe he's just too fat or its just wrinkles from being curled up. I don't know but water makes it go away it seems. That's my question. It could be too dry. Temperature is not a problem trust me. He spends most time on the warm side so he can't be too warm.. like you said he would seek out what he needsif they want to be cooler he would seek out a cooler spot so obviously he's not too warm. So he's not suffering temperature wise.
