[|Human|] my doctor diagnosed me a few yrs ago with crest syndrome although I take no medicine for it, he told me this year to get to flu shot well i didnt and came down with the flu now a week later i am still having alot of congestion in my lungs and constantly coughing, is this part of the flu or part of the CREST
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Yes, flu (influenza viral infection) can cause lung inflammation and bronchitis. Bronchitis causes bronchospasm. This in turn causes coughing, chest tightness, congestion etc. 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 albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
