Advair HFA and orthopedic

I suspect Advair is responsible for my having come down with pneumonia,stabbing chest pains( which the Dr. at the ER suggested was Pleurisy) and severe back pain in my lower back. I haven't been able to sleep in bed for at least 6 weeks and must sleep in a chair with my feet propped up on an ottoman.I have used Advair since July 2007, first 250/50 then 500/50 and now back to 250/50 in order to reduce hoarseness. The pneumonia is gone after 5 days hospitalization; the pleurisy pain has just subsided with pain killers and anti inflammatory meds . But the severe lower back pain is still there; my orthopedic Dr. has recommended physical therapy which I plan to initiate. However, stopping the use of Advair may be exactly what I need to end the back pain. I would like to mention that I did experience Thrush upon using Advair and I found that it completely went away when I started drinking pure Pomegranate juice.It doesn't taste great but it was recommended by friends during the time I had pneumonia, and lo and behold, it seems to have done away with Thrush. The Advair along with Siriva does seem to help my asma but these suspected side effects are very debilitating.
