Action point

Suffering from a persistent cough and not sure what is causing it? For a couple of days, write down at what time of the day your cough is worse.

Also note if phlegm is decreasing or increasing throughout the day. A morning cough with lots of phlegm that clears as the day progress might, for example, point to a post nasal drip.

A continuous dry cough at night, might be caused by medication.
