This morning, I swallowed a drink of water without sitting all the way up (in bed). Ever since, I have had a creaking sound in my ear, mostly when I swallow or open and close my jaw. I read that is has something to do with the eustacian tubes and air, and I have closed my mouth, pinched my nose and held my breath and it hasn t helped. It s ÜBER annoying and I need to know if this will go away on its own.
