Going Crazy

My right ear has been stopped up since we came back from Branson on Sunday. This is not the first time it's happened, but it's bugging me.

This usually happens when I fly, and it's actually worse then.  This time it's not really painful - it's just annoying to have every sound muffled on that side.  

I've tried extra hydration, leaning to the side and the other, gargling with salt water, and hanging upside down.  I REALLY hope it pops soon and goes back to normal. 

If anybody has a suggestion, I'm open to it.  If this allergy season gets any worse, I may have to hole up in the house until summer!!
