Since grade school I have these spells I feel it coming right away, I find something to hold onto sometimes sitting holding onto something is good enough other times it's so bad I end up laying on the floor. My vision goes black, all of a sudden extremely weak cant stand or walk, feels like entire body is shaking, can last longer than normal I'm afraid but literally unable to do anything till it passes. I'm aware of everything that is happening to me. I'm 35 now so this has been happening for a long time. At 19 don't know if this is related or not but I was driving out of gas station parking lot when it felt like my right arm fell asleep to the point I couldn't lift it, then this sensation went down my right leg now I'm unable to take foot off gas peddle, this feeling of limbs falling asleep continued to my left leg and arm, last my head began to feel so heavy I couldn't hold it up. I ran into guard rail cause I could no longer move any part of my body, I was scared to death I seen other customers and I tried to yell for help than I realized I couldn't talk. Eventually someone seen me called ambulance I was hyperventilating real bad by now. They would ask me questions but no matter how hard I tried I could not answer I felt trapped in my body with only my mind working. They ran many tests trying to figure out what was happening to me so it could be reversed before it get worse, they found nothing. They told my mom I'm not responsive and if they didn't give me this drug that is supposed to reverse whatever it is than I could stay the same or get worse, maybe die. This drug works or it doesn't, if it doesn't work this drug can or will kill you. So my mom had to sign my life over. I wanted to scream talking about me as if I'm not there or can't here them. They gave me drug I don't know how much time went by but slowly I could feel my fingers and eventually little by little all feeling came back and I was able to move, speech was the last thing to come back. I had severe migraine for about 3 days with vomiting than felt better. I'm very afraid that could happen again. Also I do have low blood pressure and things tend to take alot out of me faster than anyone else. What could be wrong with me? And is this serious since all test run show a healthy 35 year old, I'm active, thin I just need answers
