I work a clerical job and I have noticed when I leave work completely exhausted that my chest is a little tight and my voice fades in and out and cracks. As the evening goes on my chest gets tighter and painful and it's harder to breathe. Does anyone else haven't an asthma attack or flare-up caused by fatigue? If so, what do you do to calm your symptoms down (rescue inhaler doesn't usually work for me in this situation), and is there anything you do to prevent it? Thanks!
