Hi, I have been experiencing pain in both ears whenever I yawn, burp or hiccup . This varies from sharp to mild pain. When I yawn I also experience a sensation of a burst of pressure . Also, I get a vibration/fluttering sensation in my ears, often triggered by loud noise. Finally, I also get a crackling sounds in my ears when moving the ear muscle and a popping sound when I shout/ scream . Thanks!
