Foreign body sensation in the throat and chest pain may be caused by reflux pharyngitis and angina. 1. Reflux pharyngolaryngitis: acid reflux is caused by damage to esophageal mucosa, gastric contents reflux into pharynx causing foreign body sensation in throat, and reflux into esophagus can cause burning sensation behind the sternum, chest pain, and so on. 2. Esophageal cancer: malignant tumor in the upper esophagus can cause persistent pain in the posterior sternum or interscapular region of the back, which often suggests that esophageal cancer has infiltrated outward, causing peri-esophagitis and mediastinitis, and the pain can also be caused by the deep esophageal ulcers caused by the tumor, and accompanied by the occupying lesions at the entrance of the esophagus, resulting in a foreign-body sensation in the throat. 3. Angina pectoris: coronary angina pectoris is a clinical symptom of myocardial ischemia, which is typically described as “squeezing sensation”, “tightness”, “choking sensation”, “chest girdle sensation”, “chest pain”, “chest pain”, “chest pain”, “chest pain”, “chest pain”, “chest pain” and “chest pain”. “chest girdling sensation,” “chest weight-bearing sensation,” and “near-death sensation.” The areas of pain include the upper chest, the back of the sternum and the abdomen, and the pain may radiate to the neck, the angle of the jaw, the teeth, and also to the upper limbs, the left shoulder, and the interscapular region. If there is a foreign body sensation in the throat and the symptom of chest pain persists without relief, it is necessary to consult a doctor in time and make a clear diagnosis after a systematic examination so as not to delay the condition.
