<human>: I am a 54 yr old woman with severe bronchitis as well as moderate growth routine respiratory flora. I have had no fever, but have been coughing up green phylum.   I have been on the z-pack antibiotic also ciproflaxcin since 9/11/2012.  Still coughing the phylum and have gone through a bottle of Robitussin dm max also promethazine-codine syrup within 5 days to no avail. Can you give me more information regarding the above issues?
<bot>: Hi. I can understand your concern.  Chronic cough is commonly seen in bronchitis and lung infection. Get a chest x-ray done if it is normal, no need to worry about lung infection. Possibility of bronchitis is more in your 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, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
