I am 75 and having trouble searching questions and answers. I was told I have COPD changes in my lungs, which was surprising because I never smoked. I cough up a lot of gunk and this site has been helpful on that. I just got over the flare and use a nebulizer 2 to 4 times a day. That helps a lot. My question is..... is it "normal" to be dizzy/light-headed a lot? Any advice on that? My sats range from 87 to 94. Usually 90 or so.
