<human>: Why do I have cold symptoms all the time.  I have a bad cough and am  coughing up green mucus.  Ill go for maybe 3 or4 maybe 5 days without coughing then it starts up again.  This has been going on for months.  I have been on antibiotics 3 times.  I also have asthma but its completely under control with Dulera   My doctor or maybe I should say my nurse practitioner is diagnosing it as allergies.
<bot>: Hi, If you are diagnosed with allergic asthma then these symptoms might be exacerbation of your asthma. The green mucus shows also an infection in your lower respiratory ways. I think you need to do a spirometer test and then to be treated with inhalant corticosteroids, bronchodilator and other complementary treatments. I hope this answers your query. Furthermore, I remain at your disposal in case further medical assistance is needed.
