What does gray phlegm while coughing indicate?
Patient: , may I answer your health queries right now ?  Please type your query here... I've been having a soar throat where it feels like I have a peice of bone stuck on the one side of my throat. I cough,and when I cough I have a grayish green phlegm. I also notice that during the mid day it goes away,at night it starts to come back and when i wake up in the morning it hurts the most. I looked at the back of my throat in the mirror and it looks like i do have swelling of some sort one one side of the back near the tonsil. Any ideas? Doctor: HelloAs you explain the history you should be examined by an ENT specialist for evaluating the throat and the larynx better with a laryngoscope.ReagrdsDr.Jolanda
