I know that there are a few posts on laughter as a trigger for asthma attacks, but wondering if any of you have had an attack so bad that you could not breathe? I have mild to moderate asthma, mostly allergic and exerberated by exercise. The couple of times I have been rushed to the doctor and put on oxygen, I was still able to breathe even with a tight chest etc. A couple of time now recently when I have been laughing hard at a friend being funny or just today watching a funny movie, my chest closed up momentarily and I could not breathe at all. The only other time I felt this way was when falling off a horse and getting winded. It is terrifying!! As soon as I am able to take a little breath I cough and cough, almost to the point that I nearly throw up. Only when I can get a little air in can I use my inhaler. Anyone else react like this, and what do you do immediately?
