Ball not eating, constantly cold and sneezing.

We just got a ball about a week and a half ago. She won't eat, feels cold constantly, and sneezes. Her enclosure is kept at around 85 degrees. Advice?

First.... is her whole enclosure 85? Does she have a hotspot of 88-90? If not I'd immediately get one. Next call a hero vet, she shouldn't be sneezing.

What is the ambient temp? Is 85 ambient, or just a hot spot.
She shouldn't be particularly hot to the touch anyway since her body temp is the same as the environmental temp. And if the environmental temp is lower than your body temp, you're going to think she's cool.

So currently, bump up your hot spot to 95.
Is she making any popping noise? Is there any mucous or bubbles coming out of her mouth or nostril?
Sneezing?? Never heard a snake sneeze.

could the sneeze you're hearing be actually a hiss?

how do you say it's cold? a temp gun can be used to measure a snake's body temperature. you wouldn't be able accurately tell that by touch alone. and i think a ball python will die of overheating before it reaches a body temp that feels warm to your touch.
