Advair Diskus and knee problems

I started on Advair 250/50 6/28/07 for continued wheezing, bronchitis problems even though I quit smoking 12/25/06. In mid July I began to have Lt knee pain, the dx from the Dr was "arthritis--you are getting older you know" I was 46 yrs old. I got a cortisone shot 7/24 since the pain was so terrible, the shot gave we 1 week pain free, then 8/10 I had #2 shot, same knee, again this shot only lasted 1 week, then pain returned with a vengenance. End of August I had an MRI done on Lt knee due to continued knee pain---this showed a menescal tear. So we are in the 1st week of Sept and the pain continues to worsen, now I have pain in Rt knee also. Grasping at various straws I re-read the Side Effects and Adverse Reactions to Advair. Imagine my surprise/shock to read under Musculoskeletal: arthralgia (Severe arthritic joint pain), bone and cartilaage disorders, muscle pain, muscle stiffness. Also wt gain.
Needless to say I quit the Advair..Even tho I had been on Advair for less than 1 month before my knee problems started . Next week I go in for surgical repair on torn menesci Lt knee, and so far so good with my breathing, but tomarrow I tell my Dr that "I quit the Advair, and the reason why I quit."
