A dry cough, phlegm and itchy throat are likely to be acute pharyngitis, often caused by a viral invasion when the patient’s body’s resistance is reduced. It can also be an allergy. If the patient’s condition improves significantly through antiviral or allergy treatment for about 3 days, if no improvement is seen, it is best to go to the ENT department of the hospital for a detailed examination, and if necessary, laryngoscopy can also be perfected. During this period, patients must pay attention to their diet, do not eat particularly spicy and stimulating food, must take reasonable rest at night, avoid staying up late, and usually patients must exercise more to strengthen their resistance.
