Help what is this rash looking like redness on her spine?

My first thought was the same as KMG- that it's a thermal burn from being under an excessively-hot heat source. For safety, all heat sources should be controlled by a thermostat & checked on regularly- burns are not only painful for snakes, but they can be life-threatening or subject a snake to an infection that's also life-threatening.

IF this isn't a burn, it's also possible your snake has been wedging herself under something in her cage, & then scraped her way free of whatever it was. Could even be from the top of the enclosure, if she has things to climb on that allow her to scrape her body on the ceiling.

How long has she had this? Any blisters?

Is the CHE on a dimmer or tstat?

You have a IR temp gun? To check the surface temp under the CHE?

Che is on a thermostat along with uth

Well that's good.

Tell us more about the enclosure.

She just shed within the last 5 or 6 days but she just had mild scale rot which I treated with a betadine bath and she got significantly better and I just added a sanded branch in there and also a new hide but she’s had this for about a few weeks already

The scale rot was in the same area as the pink?

Last shed?

64 gallon terrarium with prococo husk substrate and a few plastic plants and plastic branches for decoration

No not really it just looked like a few little blisters around butt

I wonder if it's related. Why or how did the scale rot come to be? During your care? Or you got it this way?

I’m pretty sure I got her perfectly healthy I got her in March and scale rot appeared around mid April I’m pretty sure I was misting the terrarium to much

I wouldn't think misting would cause that. Not being there I'm at a major disadvantage not being able to really investigate.

Could it be a rub like suggested? Does it have something it can crawl under or through?
