Just wondered if anyone else has ever experienced this. I've had a horrible cough (most likely viral bronchitis) ... To start with i wasn't coughing up much, but now it has turned into a very chesty cough with lots of sticky mucus. The horrid thing is that I've had a couple of really scary episodes on waking, when I've coughed a lot of stuff out, but then my airways seem to close completely and I can't breathe back in again. I've been gasping and gasping for breath but can only continue to cough out again! It happened a couple of mornings ago and my husband was on the verge of calling an ambulance when I suddenly got my breath again. I've googled this and think it might be a " larygospasm " when the airway and larynx clamp shut. Thankfully, my cough seems to be improving and I'm feeling a lot better but this has been pretty terrifying. I am asthmatic too but this is definitely not an asthma attack.
