I was given a z-pac 10 days ago for bronchitis, felt slightly better. Mucus turned back clear from green. i am still experiencing burning in my lungs and upper back pain, plus a little shortness of breath. I get something like this almost yearly, but it usually clears with an antibiotic. When doctors listen to my lungs my airways sound clear, but I have had nodules shown in a CT Scan 3 years ago, after fighting to get an xray. What do you suggest for me to say to my doctor when i return to see him again tomorrow???
