Re: Cough for a week
If you are coughing up Green Phlem then you should see your Dr as you could have an infection, the same goes for chest pain and difficulty breathing. You may need a course of Antibiotics.
Apart from the usual medications for colds they will take their course and a cough can last for a number of weeks.
Boil a chopped up lemon and add some honey to taste. I like milk with a spoon of honey as well.
Hope you soon feel better,
