I sat next to someone coughing on the plane for three hours and 55 minutes; nonstop. I came down with a bad case of bronchitis four days later. I slept for the first three days and noticed a return of fever and saw my physician. He prescribed steroids, Ventolin, and OTC decongestant at evening time. From November 25 until today, December 19, I have improved but am still extremely fatigued by midafternoon. This is opposite to my usual energetic self. I am only wheezing minimally, but find the length of recovery excessive. I want to resume my normal exercise activities but my daily mile walk takes a toll on me by midafternoon. I usually spin once a week and take a Zumba class once a week in addition to the walking, and I cannot hack it quite yet.
"I am on day 5 of the Z-Pak for bronchitis and the only improvement I have is no more swollen throat. I cannot take deep breaths otherwise I immediately go into a coughing fit, my coughs are deep and painful, and my stomach is certainly not a fan of this medication at all. I can only sleep on my back to avoid the coughing and wheezing so when I finally do fall asleep I could sleep for days only to wake up more exhausted. I had a fever of the first day (Friday) which went away later after the first 2 pills but returned periodically throughout the weekend along with hot and cold sweats. The headaches are honestly the worst part. When I cough my head feels like it's going to split open. Seeking alternative next time."
Genetics play a role in the development of COPD.  It is more common among relatives of those with COPD who smoke than unrelated smokers.  Currently, the only clearly inherited risk factor is alpha 1-antitrypsin deficiency (AAT).  This risk is particularly high if someone deficient in alpha 1-antitrypsin also smokes.  It is responsible for about 1–5% of cases   and the condition is present in about 3–4 in 10,000 people.  Other genetic factors are being investigated,  of which there are likely to be many.
