Hi, I've had a cough for about 2 weeks, some days are worse then others, and I'm experienceing some occasional wheezing, with occasional back and chest discomfort. I have gone to the dr. and she believes it has to do with my Acid Reflux. I'm a little paranoid because I've been a light smoker (about 3 per day) on and off since I was 18...I'm 45 now. Of course I'm thinking the worst...Lung cancer! Any help would be appreciated.
