The time to heal from an untreated wind-heat cold varies somewhat due to the variability in individual recovery ability and the severity of the illness. Usually, a mild cold with no other complications can heal itself in about 1 week. If the cough, phlegm and fever are more severe, or if other complications arise, it usually takes longer to heal or even does not heal on its own, so it is advisable to seek medical treatment rather than expecting it to heal on its own. The main symptoms are fever, headache, fatigue, nasal congestion, sore throat, etc. A few patients may have a cough with sticky yellow sputum or yellow nasal discharge. Patients need to increase the amount of water they drink, keep proper rest, open the windows and pay attention to keeping warm to avoid getting cold again and aggravating the disease. In addition, patients should always observe the changes of their condition, if coughing, coughing phlegm or fever worsens, they should promptly take medication, such as Shuanghuanglian oral liquid, Lanzen oral liquid, wind and fever cold granules, etc., as prescribed by the doctor. Those who cannot be relieved need to go to the hospital for examination in time to avoid inflammation of the airways or lungs.
