I have a very uncomfortable time breathing through my nose as one nostril is always around 90% blocked. Is this normal? When I breathe through my nose, there is no air going through the blocked nostril at all. Only when I purposely block my clear nostril and strenuously inhale can I get air through the blocked nostril. The blockage worsens when I lie down which if affecting my sleep. I find it very difficult using nasal sprays because one nostril is always too blocked to inhale the spray.
