Advair HFA and pimple

I ahev been taking advair for 2+ years on and off when I was sick for chronic bronchitis and asthma. Within the last 4 months I have been on either the 500mg or 250 strength... I have gained over 30# in 3 months time and have a huge belly! I have not changed lifestyle to have gained so much weight. I kept joking marriage did it to me as I am a newly wed. Someone told me they quit the advair as they gained so much weight. SO I stopped cold turkey afraid my asthma would get worse. While taking it routinely I was having to use my rescue inhaler daily plus use of the nebulixer when at home. I have not had an attack since i went off the advair!!!! I also had severe leg pains/ aching. When we took a trip my legs and feet had 3+ pitting edema! All the edema has gone done. I have bene advair free for one week now. I was alos getting pimple like sores on my back and I never had acne or skin problems in my life not even as a teen ager.
