According to your symptoms, consider chronic pharyngitis caused by excessive use of voice. It is best to use Momordica grosvenori or boat-fruited Sterculia soaked in water instead of tea, or buy some tea instead of slow, strict and soothing, which will have a certain effect on improving symptoms. Pay attention to the rational use of sound, drink plenty of water, avoid spicy food, eat more fruits and vegetables, and wish you good health.
