about a month ago, I started having trouble with my right ear eustachian tube feeling blocked. It drives me crazy. My body doesn't seem to tolerate decongestants, so all I use is guaifenesin, drink lots of water, and use a homemade nasal spray. It was pretty constant for about 10 days, and seemed to improve....but now it's back. I have no allergy or cold symptoms. I just read somewhere that sometimes stomach acid can cause this problem. I always sleep on my left side, and it's my right ear.....so it doesn't make alot of sense, but I know anything's possible. Have any of you had recurring eustachian tube blockage without any other cold symptoms? The reason I'm considering GERD as a cause of it, is because my GERD has flared up at about the same time as this ear problem. Any ideas? Thanks!
