So for for last couple of years I have gone to the Hospital for many different things. But no answers. this thing happens were my face first starts twitching (in random spots), not big twitches, just tiny ones and they last a couple of hours. Then the last two fingers on both hands start to tingle, then my cheeks, and it moves to my legs and everywhere else. After awhile everything turns numb and sometimes it gets to the point were i can't breathe so i start hyperventilating. and as that's all happening, for some strange reason, I cant unclench my hands. When there are people with me when this happens. I hold on to someones arm and literally almost bruise them cause I can't unclench my hands. Its like an attack or something, they last anywhere from an hour to like three hours.When they only feel like a couple of minutes. Oh i also get cold and my heart rate increases to to way above normal levels. I'm only 19, these things should not happen. please help!
