Re: help dont have a clue
Someone here with much more experiance than myself will help you, but in the mean time a picture might help and the temperatures (hot side, cool side and belly heat if thats applicable) in her enclosure too. :)

That would be a burn.
Probably from an unregulated heating source. Whenever you use an under tank heater with a ball python you MUST control it with a thermostat or at least a rheostat (found at home depot for $11). If you do not use a thermostat, the heat pad will get to temps around 120*F which is plenty to burn your animal.
Also, you don't need any overhead light. If you still can, return it all. They don't need UV, they don't need daylight and they don't need a night light. The only reason you should use over head heat is if your normal room temperatures get below 70-75* normally. Then you will want a low wattage red bulb on 24/7 just to bring up the temp a few degrees.
Here is what you can do: Switch the substrate to paper towels so you can keep the wound nice and clean. Change the paper towels every time she makes a mess to ensure the wound does not get infected. Apply bacitracin, neosporin, or polysporin once every few days. Make sure it is the kind WITHOUT THE PAINKILLER/RELIEVER. That particular ingredient is TOXIC to reptiles. The regular version works just fine though.
Assuming you get something to regulate your heat source and you get some good accurate thermometers the burn should heal in a shed cycle or two.
