So, for the past few years I have noticed an occasional thumping sensation/sound in my right ear (only right ear). It is not related to my heart beat. A few months ago, I noticed that while the microwave was on, thumping would occur in my ear and get faster/harder as I got nearer the microwave. It would be alleviated when I moved away. Noticed a similar phenomenon with the heater in my office. I have also recently found that my ear will thump in the bathroom at the office, but only near walls and only when the heater/fan is on. Thumping gets louder/faster as my ear gets closer to the wall and gets better as I move away. My ear does not feel quite normal afterwards in any case, although "popping" my ears seems to help a bit. It isn't painful, just unpleasant and odd.
Forgive the rambling, I'm confused by this and wondering if it is something I should have checked out. Many thanks.
