Hello Rebecca. The yellow discharge from your nose could have been due to infection or chronic common cold. It is common knowledge that infection turns the secretions yellow. But a clear yellow discharge may not necessarily mean infection . Long standing cold can lead to thin yellow discharge.
What does Yellow Phlegm Mean. Yellow phlegm means that you are suffering from cold and flu or your upper respiratory tract is under the influence of some microbial infection. Dark yellow phlegm or thick yellow phlegm indicates an infection of lower respiratory tract or sinuses. It can cause an accumulation of the phlegm in your lungs and upper respiratory system and result in more serious problems. 2  Coughing helps in removing the mucus from your body. 3  Take some good expectorant instead in order to eliminate yellow phlegm or yellow green phlegm that is being produced.
