There are two causes of congestion, one is acute inflammatory infection and the other is chronic inflammatory stimulation. Acute inflammatory infections are often acute tonsillitis, acute pharyngitis, and these inflammatory infections lead to mucosal congestion, edema, and lymphatic follicular hyperplasia in the throat, resulting in dry throat, sore throat, difficulty swallowing, painful swallowing, and in severe cases, respiratory distress. In terms of treatment, because it is a hemolytic streptococcal infection, it can be treated with oral cefixime, amoxicillin, and penicillin V potassium tablets, and nebulized inhalation is needed to reduce congestion and edema in the throat, which can heal in about a week. Chronic inflammatory irritation is often caused by recurrent tonsillitis, prolonged intake of spicy and irritating foods, or acid reflux due to gastrointestinal dysfunction, acid water and acid gas stimulation that causes throat congestion. In this case, patients need to avoid colds and exercise, as well as not to eat spicy and stimulating food, a light diet, exercise after meals, less shrimp and crab and other foods, and can take oral treatment with Slowly and surely or Erdene granules.
