i've had the same symptoms for years. been diagnosed with copd. but my results of blood gas were normal. i haven't had any other tests to speak of but my question is this. i was diagnosed with asthma app 10 yrs ago. i'm now 49, and i've always had the pghlem probem. until just this week. for two days i was constantly coughing up the yellow/greenigh pghlem. why now, after all this time am i coughing up the colored pghlem?
Wheezing is a non-specific sign that can occur with asthma, bronchitis, airway collapse such as with bronchomalacia, bronchiectasis, a foreign body, excessive mucus that is difficult to clear or a growth in one’s bronchial tubes. And there are other causes. Greenish thick phlegm is definitely not characteristic of asthma, except when associated with a condition called allergic bronchopulmonary aspergillosis (ABPA) or allergic bronchopulmonary mycosis (ABPM) but then mucus plugs are expelled, not thick phlegm.
You had a “normal sputum test.” What kind of test? Was the sputum cultured for fungi and tuberculosis (TB)? That should be done. Given that this has been going on for 6 months, it is probably time for you to have a CT scan of the lungs and/or a bronchoscopic exam. If your pulmonologist is unwilling to proceed with further testing, then yes you should seek a second opinion.
Good luck.
