Oh Yoo hoo, medical experts out there in CD land, help! My left ear keeps popping, without provocation. I have not gone swimming. I do have a sniffle going on, for about 3 days. But that's it. Could it be a wax build up or fluid behind the drum? I looked up some stuff on line and by far the most common response and suggestion was to clean out my ears using warm water flushes, steam, and peroxide with w baby ear syringe. So? WWYD? Thanks!
