Sore throat after talking too much is actually caused by inflammatory stimulation, because talking too much can easily lead to vocal cord fatigue, and may also induce inflammatory reactions in the throat and oral mucosa, so there will be a significant pain sensation. Inflammatory irritation also includes bacterial and viral infections, stimulation by external environmental dust or adverse physical and chemical harmful factors, and dietary irritation may all cause inflammation and throat pain. Therefore, you should also pay attention to the frequency and tone of your speech. If you talk a lot, it can easily lead to the occurrence of vocal cord nodules or polyps, which can also lead to hoarseness of the voice.
