What are ways to stop sinus drainage?

A healthy sinus actually drains 1-2 liters of mucus per day! The problem  comes when the drainage is blocked by swelling of the nasal lining or there is an increase in mucus production from a common cold or nasal allergies. A sinus infection and nasal polyps can also cause excessive nasal drainage. Each of these conditions is treated differently. To makes things more complicated, many times we perceive acid reflux as post-nasal drip. If your own management of sinus drainage is not working, consider visiting your otolaryngologist for a complete nose and throat evaluation.
