I am in the early year stages of COPD. I've had it for a while but I'm just starting to get more and more out of breath. I can walk but it's hard for me to walk and talk. I can catch my breath pretty quickly at this point though. I just got my nebulizer and I'm waiting for my prescription for the medication. I'm scared because I don't know how quickly it progresses from here. Has medication through nebulizers helped any one?
