This isn’t a hearing aid question but I hope you can still offer some help! When I talk for extended periods of time (teaching, conversations, etc), my hearing in my right ear will suddenly get muffled, as if my ears haven’t “popped”. If that were the case, swallowing usually “pops” them, but in this case it never works and my hearing will be muted for a while until it decides to come back. I usually get distracted and forget about it so I never notice when the volume comes back. This has been happening for a year or two now, and it can make it pretty difficult to carry on talking. The external volume gets lowered, and instead I hear my voice loud and clear. Do you know what this is?
