Thanks for your question on Healthcare Magic. I can understand your concern. Pneumonia is known to cause bronchitis (inflammation of airways). So you are mostly having bronchitis because it causes excessive mucus expectoration. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test). PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Oral N acetyl cystine (NAC) tablet is also beneficial. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
