Vocal cord polyps are a very common condition in otolaryngology. They generally do not cause pain because they are a disease caused by talking excessively or improper pronunciation over the long term, rather than an acute inflammation. Therefore, pain from vocal cord polyps is rare. The main symptom is hoarseness. Vocal cord polyps are caused by excessive talking, which over time leads to thickening of the mucous membrane on the surface of the vocal cords and even hyperplasia, forming minor lesions. This can cause incomplete closure of the glottis, resulting in hoarseness, difficulty reaching high notes, and other related symptoms. It is very rare for vocal cord polyps to cause pain, and this is not a main symptom.
