i agree with slim. She will more than likely rub this off though, as hot glue tends to peel off of skin after a while. She will probably lose some scales, and so keep an eye on it. It may blister. She will probably have a little scar, but it will more than likely fade. aww, i'm sorry, poor thing! Our bolivian boa got a burn from her UTH...we had her on a shelf, and the glass was black, and i didn't realize it was getting so hot in this one spot where it was against the glass. Of course, she had to find just that spot. She had a blister on her belly, and we kept some medicine on it. She healed up and shed off most of it. She's still a baby so as much as it's faded with the past few sheds i think it will clear up as she gets older. i felt *awful*. So i've been there!
Edit: i would *not* try a warm water soak. Warm water on a burn feels horrible. You may try a soak, but i would actually just try a damp pillowcase instead, or moss for her to rub in on her own. I would try to keep heat off of the area if you can.
