Suggestions: I suggest you have a good rest, drink plenty of water, eat more fruits and vegetables, eat less spicy and stimulating frying diet, rinse your mouth with warm salt water in the acute stage, drink plenty of water, take Qingrejiedu granules or Banlangen granules appropriately, and take anti-inflammatory drugs, such as cephalosporins, if you have phlegm. I wish you a speedy recovery!
