I have had vasovagal syncope once in the past when I was dehydrated and had taken a laxative, which caused pain during defecation. Tonight I fainted after taking too big of a drink of my carbonated beverage (which I do not normally drink sodas) and it got stuck, causing pain, and I fainted. I simply put down the drink, grabbed a railing, and eased down. I am not sure how long I was down. As I swallowed, I was trying to respond to someone which may have caused me to rush the swallowing process, getting it stuck. Was tonight s fainting similar to vasovagal syncope and nothing to worry about?
