I've seen a lot of discussions that are sort of similar to my issue but not exactly. A week ago I had a cold with lots of congestion and had to travel on a plane. When the plane landed my right ear popped but the left felt all clogged, so I plugged my nose and gently blew. Nothing happened. I tried again a couple hours later - again, just a gentle blow, not violently - and my ear "popped" with a sharp shooting pain. But it didn't get rid of the clogged feeling.
It's been a week and my left ear still feels full, clogged, and muffled. No pain but minor ringing at times. I don't think I have an earwax buildup. I'd estimate that my hearing in that ear is at 50-70% of its normal capacity. My congestion in my nose/throat has totally cleared up by now. I've tried yawning, swallowing hard, stretching the outer ear, chewing gum, etc. - all the techniques for getting your ears to pop - but nothing has made them pop again or cleared the blocked feeling.
I'm worried that when I "popped" that ear I actually ruptured my eardrum. Beyond seeing a doctor as soon as I can (I'm still traveling for the next week), is there any way to identify what's going on? Or how to fix it??
