Twice in the last two weeks, my right ear feels clogged, and all sounds seem to echo.
I tried yawning, nose blowing, and it does not seem to help. The symptoms seem to disappear independently within an hour or so. The first episode was accompanied by a severe headache. What could be the possible cause of this?

I suggest you should see a doctor about your distorted hearing.
