Good evening. My problem is sometimes my throat is itchy. Everyday i spit up phlegm, sometimes white, sometimes yellow , other times brown. Few times it has trace of blood. I've been to ENT 4 times the past months, and have taken medicines including antibiotics for 3 weeks. The doctor advised me, if the blood continues, he suggested me to see a doctor for lungs. he had given me another medicines good for 2 weeks. But seems the same..One month after I've seen the blood spots in my phlegm again early in the morning. What do you think is my problem? Thank you very much.
