The feeling of blockage in the throat when singing is often associated with chronic inflammatory diseases of the throat. The specific reasons include excessive use of voice, diet and environmental factors, as follows: 1. Excessive use of voice: Patients may normally use their voice too much. 2. Diet and environmental factors: Excessive smoking, drinking, eating spicy and stimulating food, and air pollution may cause chronic inflammatory disease in the throat. Patients may also have more lymphoid follicular hyperplasia in the throat, causing further aggravation of the symptoms of foreign body sensation and blockage in the throat. If the congestion persists for a long time, further laryngoscopy is often needed to check for the presence of various benign and malignant growths in the throat, including cysts, polyps, papillomas, and various types of malignant lesions.
