question: I have acute bronchitis and heard my dr mention lung spur. What is this? I smoke (not since bronchitis though) 10 a day for 30 years. Now I m coughing up blood mixed with phlegm and very loud wheezing that is so severe it keeps me from sleeping. I have been given prednisolone and clarithromycin, a clenil modulite 100mcg inhaler and a ventolin inhaler.
