I went to my ENT doctor today to get results of latest CT scan.
Apparently my ethmoid sinus problem (per the December CTs) was more
that the scan picked up a sinus infection that never went away.
Fortunately, I had switched doctors, and this doctor put me on 21-day
Levaquin, prednisone and decongestant - then I did the 2nd CT scan a
couple weeks ago.  Sinuses clear.  Only abnormality was the presence
of a deviated septum (which the first doctor operated on 10 years ago,
and which apparently didn't hold).

In any case, if my experience means anything, getting a 2nd opinion is
vital to your health.  By trying other options (ampho-B,
irrigation,and especially the 21-day antibiotics) an unnecessary
surgery was prevented.

And the doctor said I didn't need to do surgery on my deviated septum,
unless I was finding it hard to breathe.  I don't have that problem. I
didn't have that problem back in 1995 either, but I let the first
doctor operate on me thinking it would help my recurrent infections.  

The planned course from here (on advice of my ENT today) is to see an
allergist.  He said it would take about 18 months of shots to build up
my immunity.  Also, I am supposed to keep taking Nasonex, and Astelin.
On my own, I will continue to irrigate as necessary. As you can
imagine, I can quite happy that I'm going to be spared the pain and
trauma that would have awaited me.
