Yeah let him rest a bit and leave him be for a week or so,i bet he is prob really stressed.
The hides you have are also to big,you want a hide that he can barley fit into to feel safe and secure other wise he will still feel venerable and unsecured in the hides which could lead to stress and him going off feed.
What you are using to measure your temps is most of the time inaccurate so your temps may be way hotter or colder then what you think,he may be trying to escape from extreme heat of the enclosure(just a guess),the general and accurate way to go is with a digital probe thermometer or infrared temp gun. If your humidity gauge is right then it is to low you need 50% - 60%.
You also want two thermometers,one for the cool side and one for the warm side to measure your temps on each side,whose to say there is just a 2f difference.
Have you tried feeding live? Judging from what some one else has posted about what the bump may be then,maybe the snake was only feed live where he came from,so try live just keep a really close eye.
I am no expert so take what i say as a rough guess.
