Imo: for the safety of your snake. Contact a local specialist or known breeder. Sounds like way more than a shed issue. There will always be people that argue health and care. For the most part i pick up side tricks from forums and keep my real questions for up close and personal whereas someone registered handles my snake and her health and that's how i keep it. No risk of johnny dingleberry giving the wrong advise. Best to play it safe than be irresponsible.
Example: i hate store bought uth and only use seed starter pads for hydroponics systems. While still a heat pad, They are designed to never exceed 10degrees above room temp and have a built in sensor to make sure. Yes i tested it myself every way possible... over and over and over... a year strong and still working perfect no controls needed
but thats just me.
