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. Doctor says fluid behind ear after checking me out and looking into my ears, so I'm on flonase and Allegra-D. Today I'm sitting here, still on the stuff, and it's happening again in the right ear. Last few times I noticed it, it was when I had alcohol I thought, but doctor said probably coincidence.
