I have asthma. Three weeks ago, I started with a sore throat. Finally after a week and a half, the sore throat left, but, then a cold never developed. Instead, my chest became congested. I went to the doctor, and she put me on a z-pack. I finished the pack, along with taking albuterol for breathing sessions. I still have a cough, and went to a walk in today, and the doctor thought I might have bronchitis or pneumonia. I usually take prednisone for my breathing difficulties. Will this help with the possible broc/pne? She suggested 5 20mg. a day for 7 days. Has anyone had an experience like this? I am leaving on a cruise Sunday, and do not want to be sick. If you can help, I would appreciate it.
