This is an update to previous posts.  I had posted previously that
largely out of desperation I experimented on myself by using the
antibiotic Cephalexin in my Hydropulse.  I had tried irrigation for
lengthy periods using both isotonic and hypertonic solution, with
little improvement.  The Cephalexin had been prescribed for an ingrown
toenail and I knew from past experience that all I needed was a topical
antibiotic for that, so I saved the Cephalexin.

Once I began irrigating with Cephalexin (twice daily) my sinuses
improved tremendously.  This lasted for a decent amount of time but
then regressed somewhat.  When I ran out of Cephalexin my sinuses
returned to their previous state, which allows very little airflow
through my nasal passages.

I tried Betadine twice daily to no avail, which makes me wonder if
bacteria was my problem at all? I had read elsewhere that irrigation
with antibiotics can help a lot in some cases simply by acting as an
anti-inflammatory rather than antibacterial.  I wonder if my problem is
entirely inflammation and swelling.  I do produce a decent amount of
mucus during cold weather especially, but it is never discolored which
would suggest lack of bacterial infection?

I should also mention that Alkalol didn't help a bit, either.  If
anything it made me produce more mucus.

I'm not sure what to do next.  I am wondering what irrigation with
antibiotics on a permanent basis would do and how much might be
absorbed systemically? Could it still be bacterial, even though I have
no discolored mucus? (Despite producing way more than I would like)
Fungal? I'm really discouraged at this point.
