If sore throat is considered to be caused by allergy, after exposure to allergens there will be hyperreactivity of airway and manifestations of airway spasm, such as wheezing, shortness of breath, coughing, coughing up sputum, laryngeal edema, throat discomfort, and in severe cases it may cause asphyxia. If you have allergies, you should try to identify the allergens and not to contact them in your daily life. Once allergic laryngitis occurs, you should actively treat it by giving anti-allergic treatment quickly, as well as hormone therapy and bronchodilator drugs to relieve the symptoms as soon as possible.
