Nasal polyps: Nasal polyps don't cause phlegm or mucus, but both problems may have the same cause. Nasal polyps usually are due to allergy, and allergy certainly can cause phlegm and mucus. If you have diagnosed nasal polyps, it seems likely you are in the care of an ENT doctor or allergist. S/He is the best resource for these questions.
