Yellow nasal discharge and yellow phlegm from cold will usually clear up in a week or so, but the exact time varies from person to person. Yellow nose and yellow sputum is one of the typical manifestations of wind-heat cold, which is mainly caused by external wind-heat, and can be accompanied by nasal congestion, sneezing, cough, dry throat, sore throat and other symptoms. The main treatment is to cool the surface, clear the heat and detoxify the toxin, and at the same time can be assisted by acupuncture and massage. Secondly, oral medication to clear heat and remove dampness, cool the blood and detoxify the toxin can be taken under the guidance of a doctor. After timely and proper treatment of wind-heat cold, yellow nose and yellow phlegm will mostly disappear within 1 week, and the prognosis is usually good. Patients with wind-heat colds are advised to drink more water, ensure sufficient rest, avoid spicy and stimulating, greasy food, and focus on light and easily digestible food, as well as exercise more to promote sweating and strengthen their resistance. If you feel unwell, you should go to the fever clinic or infection department of the hospital in time.
