Hi Guys i am new to this site. I have been trying to deal with Health Anxiety for a few months now and its driving me crazy. I would like to ask a question if anyone can help. For the last few weeks i have been coughing up brown phlegm throughout the day. I am a 27yo male and i am a smoker i have been smoking since i was in my late teens. I went to see the doctor about it a couple of weeks ago and she said it could be an iinfection, Smokers cough or even though i am young she wanted to rule out cancer so she sent me to get a chest x ray. I was so scared i really didnt want to go it took me 3 days to convince myself to get the xray. I got the results back and i got the all clear my lungs were clear and my heart was a normal size. I am still coughing up brown phlegm on a daily basis. Any ideas? It gets me down i know i should quit smoking and i plan to i go overseas on a hiliday in 2 weeks and i told myself i would quit when i come back?
