My left nostril is contstantly has a plugged feeling, but there s really nothing coming out when I blow and I m not sick. This has been off and on, mostly on, for a couple years now! The only way I can breath for a few seconds out of it is to pinch my nose closed and blow as hard as I can. As usual, my nose (or sinus) squeaks loudly and I feel a huge pressure build up in my sinus, then I can breath clearly for a few seconds, then it seems to swell shut. I d really like to know if there is anything I can do to get rid of this, or at least be able to breath normally again. It feels like there is a cavity in there or something, and sometimes my left eye looks puffy when I m having this problem.
