Asthmatic w/ Bronchitis: does it ever feel like u have weights on your chest?

I have Asthma/Bronchitis too.Yes, the tightness feeling is normal.It feels like someone is sitting on my chest & i have to fight to get every breath.It's scary when you don't know if you can get one more breath.Like the old commercial says,"If you can't breathe,nothing else matters".That's very true.Good luck to you & me both.
