<s>[INST] I have a constant light cough. A clearing of my throat. It feels like a constant ball of phlem in the back of my throat that just hangs there. Will not move. I have had this since mid February. Without much relief. I had a surgery on my sinuses in October but still have no relief. [/INST] hi!I think that all your problem is at your sinuses..cough and phlegm persist in the morning where the sinusitis (inflammacion of sinuses) persist In that case the phlegm which product in sinuses during the night go to the throat and you have cough as a reflex to push out phlegm.Its time to reconsult with your ORL doctor and begin the treatment ! </s>
