I'm 68. I had acute bronchitis 7 months ago. This past month I bring up clear phlegm. I don't have a cough-I just cough when I feel congested?

In brief: Irritated bronchi

Clear mucus generally indicates some inflammation (irritation) without infection.
If you never smoked or had asthma, this might be allergic or due to an irritant, or might represent a response to a mild viral infection. If you get a fever, your mucus changes, or if the cough worsens or persists longer than another week or two, you should see your doctor.

In brief: Coughing

Post nasal drip from sinusitis or from allergies can cause cough (other allergic symptoms:sneezing, runny nose, itchy eyes, needing to blow nose).
Exposure to an irritant and acid reflux from the stomach can also cause cough. If a smoker, chronic bronchitis or lung cancer can cause cough, but usually not clear phlegm. Other causes, also. If unclear reason, worthwhile seeing your doctor.
