I Am Scheduled To Fly 5 Hrs In 36 Hrs.

I am scheduled to fly 5 hrs in 36 hrs. I have bronchitis and shortness of breath especially when doing something a little physical. I have been on antibiotics for 1 week and two inhalers. My doctor did not prescribe prednisone. Less than six months ago I had bronchitis and asthma symptoms so intense that I coughed up blood and could hardly talk without laboured breathing. Prednisone was needed to clear up the inflammation. Should I travel?
