Neg allergy testing, successful sinus surgery, use daily saline rinse but chronic copious thick post nasal drip for years. What are possible reasons?

In brief: Allergy?

Many sufferers of chronic sinusitis are made miserable by environmental allergens that aren't on a standard allergy screen, or show a false negative reaction.
I suggest repeat testing along the way to rule out any false negatives. Surgery can affect secretions and ciliary function on a sort-term(1-3 days) basis.
