Initially I had a fever - and got cured but cough - It's been more than 3weeks now I'm undergoing cough with wet mucous associated every time i cough. At the times when I cough hardly I could fell the vibration inside my head above forehead in front. And the intensity of the cough is between minimal to moderate. And when I take a deep breath and breath out - I could feel some sound near to my chest (not all the time). Pls advise
