I have been fainting on and off for the past 4 years now. My doctors ran tons of test and came up with the result that it has to do with my stress level. When I pass out I am non responsive for the most part. The only thing that I can control is one muscle in my calf. I can hear everything that is going on around me. My mother and I worked out this deal by movement from my calf 1 is yes and 2 is no. The longest time that I ever passed out for was 45 min. When I wake up I have coughing fits, trembles, and I am ice cold. Does anyone else experience this??
