I would say that he'll get over it with time, handling is not the way to go in this situation especially with the RI, it'll just cause stress which will make the infection worse. With the RI situation, is he still eating? That's usually when I get a good look at Karma's mouth.
I'm just curious, but why the increase of temps? Wouldn't the hot spot being 100 be too hot, even if the snake does have an RI? I've never heard increased temps holding off/treating an RI...
