I recently was examined by an ENT Doc that I had seen several years ago with
the same complaint.  He was not very encouraging about my clogged nasal
passages but did note that a polyp was blocking my right sinus. I have
learned to live with breathing through my mouth.  The Rx for Nasacort was
his only help but my hmo will not pay the high price for this med and from
previous experience with using it I never got good results.  In the course
of talking to him I asked about a procedure that can clean out the tear
ducts. I was interested in this because when my eyes tear up the tears go
down my cheeks instead of into my nasal passages. I have the opinion that if
lacrimal fluid could pour into my sinuses it would help to clear them.   He
told me that only an ophthalmologist would undertake this procedure.  I am
curious to know if others have this problem and if they have ever had the
procedure done.  Thanks.
