Had flu 4 weeks ago. Been coughing ever since. Is it worth phoning the dr? I had green/brown phlegm, then clear, then came back, now clear again. Horrendous at night and none of the pharmacies have ~anything~ night nurse although I did get an alternative which helps some nights. Not sure if it's something that needs to run it's course or if I should ask for treatment from the GP? No issue with getting an appointment, they are excellent.
