For some people, taking a very deep breath makes it go away. I know it feels like the worst thing to do and you want to breathe shallowly but if you can try it you might get relief next time.

I have done this as a kid. The pain was pretty severe and there was a noticable "pop" followed by relief. So it's definitely a way to fix it, but my god it's spooky.
