I am a 23 year old male that has smoked off and on for the past 8 years.I just recently quit ten monthes ago, smoking on few occassions where I gave in.At the end of 2005 I went to the doctors due to some congestion where they prescribe an anti-biotic.After the doctor's visit I went on vacation to Bulgaria in the first week of 06.This discomfort continued so I visited a Bulgarian Doctor where he administered an x-ray and something was noticed in my lungs.He believed it was just an infection and explained the lung cancer is unusual at my age.After taking the antibiotic and returning home I still had the same discomfort/feeling of congestion.I returned to my physician where they perscribed a medicine to help with the congestion,a steroid inhaler,a albuteral inhaler, and I did a nebulizer (not sure how to spell this).After the nebulizer I felt better. I took the decogesting medicine and use the inhalers as perscribed. On Jan. 24 2006 I got a gym membership and performed excercises with no difficulty. Running up to 4 and five miles on the tread mill with other weight excercises.Not once while attending the gym did I have any difficults breathing or pains,but still occasionally had this congested feeling in chest and a lump when swallowing. At sometimes I do not notice this feeling, changes in posture or air can bring it back or seem worse.I just recently went back to my doctor and had an x-ray again.I am waiting on the results, but figured I would get some more advice before I get the results.I also have a history of brochitis.I would just like to know thoughts on this matter.
