Thank you, the OP didn't mention "mild" per se. He described it as "my snake I think has a possible burn, it's a pinkish/brown line down his stomach, no blood and no puffiness", I've never seen burns in person only from experience on here and pictures and friends, but it sounded to me like a mild burn. I agree pictures would definitely be more helpful, which is why I said "for a mild burn do this" kind of thing. I had never heard that petroleum based ointment on a mild burn was a NO-NO, which is why I wanted to ask here because I trust you guys more than anythingand I wanted to make sure I wasn't giving out bad advice.
