“What happens if you use really hot water with your Neti Pot?”

I was impatient last night and didn't wait long enough for my boiling water to cool. It hurt a little at first but because I haven't been able to breathe for the past few days I figured hot water would help. I've been reading that too hot water (which it definitely was) can cause internasal tissue damage.

What can I do to help repair the possible damage done? Will it heal on its own or do I need to see a doctor?
