What does this look like to you????

Calm. I think it looks something like a mild burn too. The first thing to to figure out where it came from, the obvious choice is the t-stat is reading wrongly or it is allowing high spikes, are you keeping the snake in a tub? Check the temps on the bottom and wait until the unit clicks on and measure the temps carefully for 4 or five min keeping an eye out to see if you get a sharp increase that can happen with this sort of t-stat. I have the exact model that I use to back up a herpstat. If I get a chance I'll play with it tonight and see if it spikes and how high it does.

The first thing is to figure out
A/ is it actually a burn, can you ask someone with more experience near you to take a look?

B/ if it is a burn (what it seems to be... hard to tell for sure from a picture) discover how the snake got burned in the first place and fix it, so it doesn't keep getting worse.

Keep things clean and dry and solve the where it came from problem, everything should be ok. Keep notes of when and what you have done photos of it daily so you can see if it is improving or not. I could also be a shed sign and a mild burn so a shed maybe coming soon (often they will shed if there is damage to the skin).

Good luck and keep us posted on the progress and what you discover.

Thank you so much for the help, and my thermostat probe is right on the warm side under the hide and my thermometer probe is under they hide as well on the warm side were my heat source is, i use a sterlite tub and have a zoo med under tank heater.

So first thing tomorrow i am taking out all of her aspen and switching her over to paper towel until her next shed, and the only exotic vet around me is closed until Monday,So should i also take out the decor and should i give her a soak and apply neo sporin just to be safe?

Tomorrow i will play around with the temps on the thermostat and thermometer and check if anything is not right.So does this sound about right to you guys ?
