Soaking them in 95° water? Nope, whoever told you that was inaccurate. However you can help them by raising the temperature on the cool side, and if you can, possibly the hot side, assuming it's not where it's suposoto be at already. The only thing that can cure RI is a vet though.
EDIT:
When I say help them, I mean prolong any long-term damage, or from them getting any worse, while you wait for the vet, but it won't cure them, only antibiotics can do that.
