WOW! I can't believe what I'm hearing. I have been on Advair for almost a year. 500/50 dose. I have severe asthma and it was my only hope of getting off oral steroids. YEAH it worked! I even lost 60lbs do to being off steroids. But about 5 months ago I woke up with horrible pain in my muscles. They haven't let up. It has been hard to go about my daily life. I can't walk sometimes and it feels like I have arthritis. I have been to several docs and no one ever mentioned Advair as a possible reason. I now have to wonder after being diagnosed with Fibromyalgia. That is how bad my pain is. I also have repeated sinus pain. I had sinus surgery but the pain is still awful. I have ear pain, throat pain, mouth/tongue pain. My anxiety has been so bad over all of this. I will talk with my asthma doctor about this.
