Asthma under control; yet, coughing up stuff and breathlessness, on occasion.

[OldnWheezy]

My asthma is allegedly under control and not too bad, as measured by peak flow and spirometry tests. Nevertheless, I have periods of breathlessness, cough, and bringing up yellow stuff, deep within my chest. This last symptom just occurred a week or so ago; have finished some antibiotics for it. But I don't really understand what's wrong with me. The poor air here (from Canadian wild-fires) hasn't helped, either. Ideas of dx? Thanks.

Is it asthma causing the symptoms would be my reaction. I would ask your doctor if there was another lung condition starting to bother you.

Have you tested yourself or been tested for covid recently? And have you had covid?

Wondering if oral steroids would be helpful?
