Doctor I am getting phlegm from last 3 months. It is not resolving , I have tried medicines but I have to clear my throat frequently but I don't have any cough. Last month I was getting blood in phlegm.The blood like thing in sputum I only get after brushing and after taking bath with cold water. But rest of the time I don't get blood in sputum. I had done CXRAY, GeneXpert, and also CT chest with contrast but all are normal. I only get like this type of sputum after taking bath with cold water and after brushing my teeth in the morning but rest of the day my sputum is normal. I don't have any weight loss, fever , fatigue . Sir what to do ?
