Sinus drainage is excess mucus draining from the nasal cavity, commonly from the nose or down the back of the throat--a condition called postnasal drip. Sinus drainage can rbe the result of allergies, the common cold or environmental conditions such as lack of humidity or moving from hot to cold temperatures quickly, according to Dr. Murray Grossan, a leading eye, nose and throat specialist in California. Sinus drainage is treated with over-the-counter medications as well as with natural remedies.
Types
Sinus drainage manifests itself in either a runny nose or postnasal drip. A runny nose resulting from allergies or environmental conditions is typically clear in color and thin in secretions. A runny nose resulting from a viral or bacterial infection is typically thick and yellowish-green in color. Consult a doctor to determine the cause of the runny nose. Postnasal drip can be the result of allergies, the common cold or a physical complication such as nasal polyps or a deviated septum. Postnasal drip may cause throat irritation, a sour stomach and a cough.
Cause
Sinus drainage is the result of excessive mucus secretions in the nasal cavity. When the sinuses become irritated or inflamed, they over-produce mucus, resulting in drainage, according to the Mayo Clinic. The sinuses are a sensitive cavity located in the middle of the head and may become irritated by lack of moisture in the air, an allergen or a viral infection.
Misconceptions
A common misconception with sinus drainage is that it is a sign that a person is sick. While a runny nose or postnasal drip may be a common symptom of catching a cold or illness, nasal drainage is the body's natural way of cleansing the sinuses. A runny nose can be the result of eating spicy food or going from one extreme environment to another such as very dry air to humid air.
Treatment
Use a humidifier to maintain proper moisture, a saline wash and drink at least six 8-oz. glasses of water daily. Take an over-the-counter antihistamine such as Diphenhydramine to dry up the excess drainage. Avoid possible irritants such as exposure to pollen, dust mites or cigarette smoke. Stay indoors if the nasal drainage is the result of seasonal allergies.
Complication Signs
See a doctor if the sinus drainage lasts for more than 10 days or gets worse. If you develop a fever lasting more than three days, consult a medical professional. A common sign of a sinus drainage complication is sinus pain accompanied with thick, greenish discharge. Bloody discharge from the nose is not normal and could be the sign of a complication.
