I haven't found anything online related to this "condition" and at the moment it is driving me crazy.
I have the flu, it is nothing serious except, many an occasion I have blown my nose and a "bubble of air" is trapped in my I assume is my sinus canals. It usually takes a few hours to eventually come out, and the sound associated is like spraying a can of aerosol or the like, which comes from my right-side of my nose, where the pressure is/was.
Why does this occur and how can I prevent this, when it has occurred, what remedy should I follow?
