[|AI|]  Hi. I can understand your concern. She is mostly having bronchitis. Since chest x-ray is normal, no need to worry about lung infection. Possibility of bronchitis is more in her case. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test). PFT is needed for the diagnosis of bronchitis. It will also tell you about severity of the disease and treatment of bronchitis is based on severity only. You may need inhaled bronchodilators and inhaled corticosteroid (ICS)Don't worry, she will be alright. Hope I have solved your query. Wish you good health. Thanks.
