It happened all suddenly. While just sitting on a sofa and playing game i caughed lightly(i'm a smoker) and couldn't catch a breat after. It passed after 1 minute but i was already on my way to catch a phone and call for ambulance. I didn't feel like my troat was blocked or anything like this - i just tried to breath and couldn't get any air inside. Please advice me what can i do if it happens again and what to do avoid it.
regards
Adam
