I have had this syncope (passing out from caughing for years) I went to the Doc today and she said I might have a from of mildacid reflux that makes me caugh a lot. She prescribed sinuus nose spray, daytime nyquil, and Prylosec (spelling) It's a new twist but she said that's why it is worse when you lie down.
We will See
I have hads these attacks for about ten years and the only thing that helps me is albuteral inhalers and nebulizer treatments. when you feel like your gonna have an attack try not to breath so deep and if possible open your freezer and breath the cold air helps me alot. I hate going to the hospital and doctors, seems like they don't know sh&$@ anymore. My Great Grandfather taught me to do this and you wouldn't believe how a little cold air could help so much. If you have athsma i would ask your doctor for some Augmentin(great medicine by the way), and medrol dose pack. Not a doctor but i think thats the ticket.
let us no ifyou find an answer it happens to me once and awhile my doctor also has no answer .... my face also turns purple when i black out tis morning couldnt breathe so i opened and stood at the back door when i started coughing blacked out and landed on top of a chain saw bashing my head into the concrete few cuts . Would be nice to no what could prevent this
