I have had asthma for about 12 years. It has progressed fast but don't believe it is emphysema yet. Stupidly I still smoke...or try to. I have used mostly salbutamol regularily and every now and again my doctor will try other types. I too have gained weight, lots of it, have leg pains and restless leg syndrome, blurred vision and fatigue. Many days I barely make to and from work. And all of these in just since taking Advair. I trust the doctors too much. Reading all of these are scary. It seems many doctors don't really have our best interest at heart. It begins and ends with money doesn't it? Another problem I have is because I am so sensitive to different thing, how can I know what is causing what??? I went for allergy tests last month and I could have told them more than what their tests showed and then some. I have since tried not to smoke and seriously looking into alternative treatments...stop the smoking for sure withpatches if I have to.
