There is no description of the cold recovery process in stages. However, the process of cold and flu can be roughly divided into three stages: pre, mid and post, and different stages can show different symptoms. 1. Pre-phase: This phase is mainly characterized by nasal congestion, runny nose, sneezing and other symptoms, and some patients will be accompanied by sore throat, cough and other symptoms. 2. Middle stage: the nasal mucus gradually becomes thicker after 2 to 3 days, which may be accompanied by sore throat, hoarseness, dull taste, breathing discomfort, etc. In severe cases, there may be fever, chills and headache. 3. Late stage: The late stage of a cold, usually the 5th-7th day of a cold. The main symptoms of the cold basically disappear, and the energy and strength basically recover. If there are complications, such as viral pneumonia, the course of the disease may be prolonged. Symptoms are different at different stages of a cold. If the symptoms of a cold are severe, you need to consult a doctor in a timely manner and get reasonable treatment under the doctor’s advice so as not to delay your condition.
