Hi. I'm 29. For the past few months i've been smoking a lot of rollies with heavy tobacco, even 20 a day maybe. I've been feeling breathless while doing some effort but for the past days I noticed i feel a little without air even at rest, especially at night. I wake up feeling i don't have enough air. I don't have cough or mucus neither chest pain. This thing happened years before for the same cause. I was smoking a lot of rollies and the same dyspnea happened. I did an xray that showed signs of bronchitis. I stopped smoking, start exercise and everything was back to normal. I used to go running a lot until octomber this year. At january I started smoking again and then i swiched to heavy tobacco. Is it possible that's just reversible bronchitis? O fear emphysema. How did your COPD/enphysema started and how bad was it when you discovered it?
