Advair affected my heartbeat, made me feel every heartbeat as if something was wrong. I also had muscle cramps, even after hydrating before bike riding or weight lifting. the unusual heartbeat went away two weeks after stopping use of advair. I also went through a peeriod of lower back pain, maybe from sore kidneys, although I tapered off of the advair slowly. I feel better after getting off of this drug, I thought ageing was catching up with me I am 62 but after stopping use of the drug i feel 40% better than while on the drug.
