Wow, I got on the internet this morning looking got side effects of advair b/c I mail ordered my script so i've been without for a few days. i have been experiencing severe neck pain, thought I slept on my neck wrong, but it's still here after 3 days. I have been on Advair 100/50 for 6 years, and have now worn glasses for 3 years, on nerve blocker medication for neck and shoulder pain, horrible heart palpitations, but I've never thought these things related to the Advair until recently. I've been asthmatic all my life and thought Advair was a lifesaver, but always had some concerns. I knew any medication could not be safe for life, and after 6 years. I'm really starting to pay a price.
