question: a certain feeling comes in/on my leg/thigh and I know I m going to faint. I do not feel it in my head, but my leg/thigh only 1. then I need to lay down and wait for it to pass, that s when I know it s in my head also, the fainting.. but I feel it in my leg/thigh. only one. If I am standing I must immediately sit/lay down or I will fall/pass out. Usually I make it to the bed/sofa/chair. that s when I notice the blacking out would be in my head.
