Okay this may sound strange but i am trying to self diagnose my (black outs), 1, have you ever felt that traveling a familiar stretch of road some thing seems wrong, the travel time seems to long? 2, Or some thing that is familiar seems wrong, like who are these people, why am i here. 3, when one gets these feelings one gets a physical sensation of imminent harm, like the feeling one gets if viewing some one having an accident, like my worst fear is getting gravel rash, i all way get a physical sensation starting from my tail bone and going through my knees accumulating with a buzz to the head. Some times a sort of black out ensues, i do not loose consciousness, i get a sort of tunnel vision, i can hear what is going on around me, but i am to weak to do any thing. I can postpone the (black out) if i concentrate, for a short time, but can not stop it eventually getting me. Any help will be valueless thanks.
