Pharyngitis is caused by abnormal immune regulation of the body resulting in the accumulation of a large number of immune cells in the pharynx, which can also cause breathing difficulties if the throat is red, swollen and congested. Medication can be used to relieve the symptoms with some heat-clearing and detoxifying drugs, such as Blue Scutellaria Oral Liquid or Chamomile Bingmei Tablets, which can reduce inflammation and swelling. You can also do a nebulization treatment with gentamicin plus dexamethasone to reduce inflammation and swelling, which can effectively relieve dyspnea and eliminate the edema of the throat. You should pay attention to drink more water, do not eat some stimulating spicy fire food, pay attention to ensure sufficient sleep, do not work too hard, try to avoid staying up late, do not be too much pressure.
