90-92 is a normal temp. I keep my warm side at a constant 90 so a bump to me is 92. My cool side is 80 with ambient temps always above 80. I've read some debate over humidity when it comes to treatment of a RI. When a human gets a RI the heat and humidity (via a nebulizer) is used to break up the gunk in the lungs so you can get rid of it. The things with snakes is that they tend to take their time getting sick and getting better. This can be a great thing when you catch something early, but when your checking daily for progress healing it can take forever. You may end up needing an antibiotic from a vet if the symptoms worsen. If you do go to a vet ask about doing a culture first to make sure you start with the correct antibiotic. Good Luck!
