Helo Sir, i have a problem, In the morning when i wake up and i cough the first time then the normal tar like stuff from smoking comes out. (a little bit black soil in color) This cough contain a very tiny amount of blood spot i inspected it myself also very well to be sure. This only happens in the morning just after i woke up, i want to notify that i sleep with my mouth open and its terribly dry when i wake up and cough the first time. There is some pain and gas in my stomach. I already went to my doc a couple of times and he listened to my lungs and everything is more then fine he said no obstructions nothing also no wheezing etc. I think that if the blood would come out of my lungs that it would also be present in the Phlegm i cough up or not? And like i said i only happens in the morning after just waking up, the rest of the day how hard i also try to get blood in my cough i does not happen and believe me i try hard to be sure. I only cough in the morning the rest of the day nearly not. What do you think doctor ?
