From last week i have fever and dry cough now fever is fine but i still have have too much dry cough it's hurting head too when i m doing cough?

Cough: Cough is the most lingering symptom of any cold. It will get better even if you don't do anything (like i do), but it may take a while. Turning it into wet cough would feel better. For that, use a humidifier. Cough drops, dark honey and pelargonium (herbal) have been shown to be effective. Of meds, i like thessalon perles and dextrametorphan.
