I flew home from Texas the other day, and while on the plane, my ears were fine and popped as normal. But a few hours after I was home, I yawned and my ear popped really loud (which is unusual for me). And once it popped, I immediately had an echo like I have a tin can in my ear and it sounds and feels like my ear is full of water. I just thought it would clear up on its own, but it has been two days, and it is still the same. It doesn t hurt at all, but I can hear something sloshing around in there like water is in my ear. Do I need to go to the doctor , or is this something that will clear up on its own? Thanks!
