If the phlegm that you have is dripping down the back of your throat from your nose and sinuses it could be postnasal drip. There could be several reasons for this phlegm. One is an allergic reaction to inhaling something. A second reason is a nonallergic, noninfectious inflammation in the sinuses that could be lingering after a cold. When the phlegm "sits" there, it can change color quite frequently. A third reason is chronic sinusitis. Postnasal drip can cause irritation of the throat and lungs. You may experience the postnasal drip as a constant feeling of phlegm at the back of your throat. A nasal wash helps remove phlegm from the nose and sinuses. This can temporarily reduce the postnasal drip and lessen the dark brown phlegm. A prescription nasal steroid spray decreases nasal swelling and phlegm production. This may prevent the postnasal drip and dark brown phlegm. To get the most out of a nasal steroid spray use it after doing a nasal wash. A nasal steroid spray does not provide immediate relief of symptoms. It may require several weeks of routine use to become effective.
