Hi, may I answer your health queries right now ? Please type your query here...i have been experiencing similar symptoms, feeling faint, things around me turning dark, cold sweat. the last time i had the experience and it was longer than usual. i don t know what triggered it or what could be the problem, but i noticed it s usually in a restaurant and especially i had different combination of dishes that were spicy. what should be my next step beside not eating spicy food?
