I have been taking advair for under a month now. I was diagnosed with cardiocondritis, (I am also asthmatic) and was prescribed prednisone for the chest pain. I did the run of prednisone, ( nasty little pills) and my chest pain eased a little. I started taking prevacid and advair at the same time and now I have this lingering pain right behind my nipple. I stopped using the advair and it's gotten alittle better, but it's still there. Has anyone gone through this? I'm 26 and I don't want to be medicated forever so any help you could give would be great cause my doctor doesn't have a clue. Another thing is I'm not even sure I have asthma, I was never tested for it and have never even had an attack. I used to smoke so I attributed my wheezing to that. Please help
