Got diagnosed with reactive airways disease. im scared that it could be copd or something deadly. im 29 years old, i probably smoke 10 cigarettes in my entire life, very healthy. only symptom is sob, tight chest and burping ?

COPD: People who have chronic reactive airway disease for years may go on to copd. Otherwise you may only periodically wheeze on exposure to certain triggers like animal hair. In between episodes you shouldn't experience sob or chest tightness. Burping is often a nervous habit of air swallowing and only causing more burping ?tension. I recommend getting a proper diagnosis by consulting a pulmonologist.
