I played sports heavily all my life, high school varsity football 3 year letterman in Ohio, 13 years of baseball, the works, and I never had breathing problems really, except walking pneumonia during my senior football season. Its been about 2 and a half years and about six months ago my breathing became very difficult, my lungs felt tight, I coughed up brown chunky phlegm, and felt low on energy, like i don't have enough oxygen or something. I smoked about half a pack a day. I was put on an HFA inhaler, after trying to fight it for two months, and it had zero effect on my lungs after two weeks. Breathing treatments were ineffective, and I was put on advair, 100/50. I quit smoking about two and a half weeks ago, and have been taking my advair for about three weeks, and I still have not improved at all. Should I continue this treatment or maybe see another doctor???
