A few days ago I became sick and have a head cold, but as of yesterday the hearing in my right ear has been feeling funny. It resembles being in high elevation and it feels like it needs to be popped. It wont pop with anything I do. It pops by itself but doesn't last for more than a few hours. It also aches a little too when it starts again, I can hear out of it but it sounds kind of muffled. Dr couldn't find any sign of infection or loss. Should I just chalk it up to this cold I have? (please no snarky comments) thanks!
