If you have a cold with a runny nose, it will generally recover within about seven days. Since this is just a common cold and it is self-limiting, there is no need for excessive worry. However, if the symptoms are more severe and include coughing, phlegm, and fever, it is important to take some anti-inflammatory and anti-infection medications along with symptomatic treatment to alleviate the symptoms. Recovery should also take about three to five days, and there is no need for excessive worry. Additionally, it is important to keep warm, avoid catching cold, eat a light diet, avoid spicy and greasy foods, cold and irritating foods, drink plenty of water to promote metabolism, and enhance your immunity. Do not stay up late and ensure sufficient sleep to help the illness recover faster. (Please follow the guidance of a professional physician when taking medication and avoid self-medication.)
