[|Human|] I have been coughing up yellow phlegm for about 3 weeks with no other symptoms other than voice hoarseness during the first week. For the past few days though my phlegm is still yellow but occassionally has a few tiny gray flecks in it. Should I be concerned? And no, I am not a smoker and I live in a smoke-free home out in the country where pollution is low.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Yes, you should definitely concern about these symptoms. You are having chronic cough (cough for more than 2 weeks) with yellow phlegm. This suggests possibilities of bronchitis or lung infection more. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Chest x-ray to rule out lung infection. 3. PUT (pulmonary function test) (to rule out bronchitis). You may need antibiotic, inhaled bronchodilator and inhaled corticosteroids (ICS). Don't worry, with proper treatment, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
