I am 46, overweight, high blood pressure, diabetic, bi-polar, and have a psuedo tumor cerbri. My body will jerk for no reason. Usually it is one sudden jerk, sometimes it will, like, go from my left leg to my right arm, when it does it in the stomach area it usually is several jerks and will literally move me from the position I'm in (thrown me in the air when laying in bed and has moved me from a sitting position, like someone pushed me from behind), I have spilled drinks on myself. Any idea what this could be? Thanks!
