Okay, thank you guys. Maybe the reading was wrong but I did have to wipe down the walls of her tub with a paper towel and it came away wet. Not damp, but wet enough to wring it out. Idk how I managed that lol.

So it's all good news from me this morning; Her tongue is back to normal and she seems fine after raising the ambient temps to 88 like Sauzo and Albert said. Thank you guys so much, I think that really helped. I'll still be checking on her carefully for a while though and watching that tongue.
