I had cough for which I was treated in September, for same, after that I had cough and irritation in throat,which if I could cough up the thick, very little yellow/white mucus , it would cease. But I have had a spot near the centre of the pigeon bone where the irritation has always been from the start and feels like a small ball sitting there when I cough. The cough had subsided a lot. Sometimes I had bad cough, as I have to speak a lot in my job, but was not consistent. My cough has become consistent again and continuously white mucus is being discharged/ I am spitting out. It is affected my professional life as I break out into bouts of cough in between my speech in class. My voice sounds broken. Please advise
