Possible asthma or cold not sure

Patient: I had mild asthma as a child and used to take puffers and have been off them for several years but recently i got a phlegmy cough and it wont seem to go away and cough medicine doesnt work even the stuff that is for mucus and phlegm…. could it be asthma acting up?

Symptoms: Coughing, weird noise when i breathe
