To distinguish between a cough from a cold or a cough from something stuck in the throat, it is important to look at the history, accompanying symptoms, foreign body sensation, and whether the cough is self-relieving. 1. Medical history: If it is a cold cough, there is usually a history of cold and the symptoms develop gradually; if it is a foreign body stuck in the throat: there is usually a history of eating granular or lumpy food. 2. Accompanying symptoms: Colds and coughs are usually accompanied by fever, nasal congestion and other cold symptoms; foreign body stuck in the throat is usually not accompanied by other symptoms. 3. Foreign body sensation: Colds and coughs do not consciously have a foreign body sensation in the throat, while a foreign body stuck in the throat can have an obvious foreign body sensation. 4. Whether it can be relieved on its own: cold and cough symptoms can generally be relieved on its own, while the foreign body stuck in the throat can exist for a long time if the foreign body is not removed. It is recommended to consult a doctor in time.
