Whether a cold can heal itself without medication is related to the specific condition, as follows: 1. Can heal itself: For diseases like the cold, if it is just a common viral cold, it may heal itself, and in most cases it will gradually recover in 7-10 days. 2. Can not heal itself: The cold may sometimes be a bacterial infection, and bacterial colds generally have no tendency to heal themselves and require active anti-infection treatment. In addition, the influenza virus can also cause a cold, a condition also called influenza. Although influenza is also self-limiting and may heal on its own, there are possible complications of this disease, including pneumonia, myocarditis, etc. In severe cases, it also requires treatment with antiviral drugs such as oseltamivir to prevent the above complications, so for this phenomenon of influenza, it is not recommended to wait for self-healing and requires active treatment.
