“I have a miserable sinus headache, Doc. My sinuses are killing me. My teeth hurt, the left side of my face is tender, I can’t breathe through my nose and awful stuff is coming out of my nose.” You’re not alone. Millions of adults (18 years and older) suffer from sinusitis at a cost of billions of dollars. Sinusitis affects about one in eight adults and costs over 11 billion dollars a year to treat.
