I have been on Advair for 2 years. After taking it for 6 months I started having severe SI joint pain, and gluteal and hamstring muscle pain. I have been in physical therapy for the past year and a half. I am still not healed but better. I just looked up the side effects to the advair and am now wondering if possibly this could be my problem?? I am very active with running...etc and have had to make some major changes due to the pain. Considering stopping the advair. Anyone else with similiar story?
