Welcome to the site!
Can you post a picture of her belly?

First thing i noticed is that your cage temperatures are low, and the thermometers that you are using aren't very good. One of the key ingredients in getting a sick snake better is providing perfect cage conditions.
See if you can get one of these thermometers from Walmart. They only cost $12 and a standard cage will only need 1 of them to monitor the entire thing.
The sensor probe will go on the hot side of the cage directly under the heat lamp(s) and the unit itself will sit inside the cage on the cool side. This will measure your hot side, cool side/air temperature, and cage humidity.
The cool side needs to be 80 degrees while the hot side should be 90 degrees these temps don't need to be exact, but try to keep within +/-2 degrees of them.
You might need to get a more power heat lamp to do this. I would recommend these bulbs for 24/7 use:

Humidity should be between 40% - 60% normally and 60% - 80% during shed.
Which brings me to a question. Are you sure that your snake isn't simply going into shed?
Once we can see what is going on we can start to help solve this problem.
