i have been taking advair for almost 2 months and a few days ago i started to have servere muscle pain in my neck and pain in the bottom of my head. I also for the first time in my life have been having anxiety and panic attacks...i didn't know what was wrong with me, i went to the emergency room and my doctor and had tons of test done with negative results!..i thought i was havening a mental breakdown! I came across this website and read all the post put up..i can't believe it...i thought i was dying, never would i have thought that the one medicine to help me breath was just about killing me.
