I am 60 years old and was diagnose with asthma, I have been given an inhaler (symbicort).  I got the flu and found it very difficult to breathe at times with my nose blocked. I get very tired easily and found it difficult to go up and down stairs.  When I do my breathing problem get worse.  Is there a cure and what can I do to help myself?
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of post infectious bronchitis is more likely. Bronchitis (inflammation of airways) is common after viral upper respiratory tract infection (flu). 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 need inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
