I can understand your concern. Acute breathing difficulties can be due to acute bronchitis or asthma. So better to consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT Pulmonary Function Test. You may need inhaled bronchodilators formoterol or albuterol and inhaled corticosteroid ICS budesonide or fluticasone. Do warm water gargles and steam inhalation 4-5 times a day.Dont worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
