Once you get an
infection, all the bacteria,viruses,allergens,and toxins take on
a life of their own. The cure is to get rid of the pustulence, with surgery--no way!--or advanced saline sinus flush. I got a Snot Demon for 7 yrs, teaching grade school/germ factory. A cold in the fall, then sinusitis, lost smell then taste, Cipro, hawk spit cough, sore throat, partial recovery in summer. Then I heard about a saline flush, like the one mentioned above.
