Finger touch symptoms and conditions

I have been on Advair 250/50 for approx 4 yrs. I am 47 now. I Know I have to take the medicine for my COPD every 12 hrs. If not, I have difficult time breathing. I had leg cramps in the beginning, but not too much now. The problem that is most bothersome now is low back pain. Not sure if I have osteoporosis setting in, or it is just a side effect. I am always coughing up mucus. My shoulders, arms, and legs, are very sore to the touch. Feels like someone has come up and slugged me, and that is just from a finger touch.
I know I cannot get off of the Advair, If does help my breathing, but I also know the consequences if I do not take it. Almost like my life line.
Does anyone else feel this way?
