I've had chronic sinus infections pretty much for years. I got a new doctor lately, who is a lot faster at seeing me, etc. Anyway, long story short lately I hear at times a thumping noise in my right ear mainly, it's only happened in the left a handful of times. When it happens in the right, it usually goes on for 24 hours at a time, obviously annoying enough to cause me some loss of sleep, aggravation, etc.
