Hi. I do not have COPD. But I have a similar disease in asthma. And have the severe type. And I can tell you that there are times when I get short of breath out of the blue. And that's what your rescue inhaler is for. Do you use that when you are feeling like this? Does it help? Because it usually helps me and gets me back to feeling normal again. And this is just normal for ME. In your case, is it your new normal?Or, are there tweaks your doctor can make to help PREVENT you from experiencing this. When you say use your inhaler later in the day, are you referring to your rescue inhaler? Or some other inhaler? John. community moderator.
