Tearing during a cold is not an indicator of a severe cold; a severe cold actually refers to more serious general symptoms in the patient. The common cold, also known as an upper respiratory tract infection, involves the respiratory tract from the cricoid cartilage of the trachea up to the nasal cavity, which is called the upper respiratory tract. An upper respiratory tract infection is essentially an infection in this part of the respiratory tract. If an infection occurs, the primary symptoms include nasal congestion, a runny nose, sore throat, and coughing. However, some patients may experience severe general symptoms, including fever, joint pain in the limbs, muscle soreness, fatigue, nausea, vomiting, and diarrhea. These symptoms often indicate a severe cold. Tearing alone during a cold is quite common and can also be seen in milder cases of the common cold. Therefore, it is not a significant indicator for diagnosing a severe cold.
